-	  #print Dwarves
-
-2005-10-21 23:20  bpk
-

-
-	* cmd.c, ptr.h: Changed #module to not require the .so extension,

-	* Initial import of stock powwow 1.2.5
-
-Changes from 1.2.4 to 1.2.5 (Massimiliano Ghilardi, ...) 21 Jan 2002
- 	* Added append-mode to #capture: use #capture >file-name
-	* Cleaned #spawned commands interface: text they print on
-	  standard output *MUST* terminate with a newline ('\n')
-	  in order for powwow to execute it.
- 	* Fixed missing #include <time.h> in main.h.
- 	* Fixed broken matching of #mark patterns starting with $
-	* Added the following user-contributed patches:
-	  * Put also 1-char lines into history;
-	  * Do not capture/movie data coming from spawned commands;
-	  * Fixed a bug in command parser.
-	
-Changes from 1.2.3 to 1.2.4 (Massimiliano Ghilardi) 24 May 2000
-	* Added support for IAC GA as end-of-prompt marker.
-	* Added #request [prompt][editor][all]
-	* Fixed missing/slow prompt redrawing under some circumstances
-	  if #isprompt <number> was used.
-	
-Changes from 1.2.2 to 1.2.3 (Massimiliano Ghilardi) 18 Jan 2000
-	* Fixed `#spawn' command that was completely screwed up.
-	  Also fixed CTRL-C not to kill spawned commands.
-	* Sending/receiving data to/from spawned commands erased the prompt
-	  instead of reprinting it. Fixed.
-	  (If you don't like powwow to show the prompt before executing
-	  lines from spawned commands, set #option +compact)
-
-Changes from 1.2.1 to 1.2.2 (Massimiliano Ghilardi) 10 May 1999
-	* Fixed `#delim custom' to accept whatever character as delimiters.
-	  Previously stopped before the first word-delimiting char (argh!)
-	* Fixed screen corruption when doing some editing functions
-	  (&del-word-right, &del-word-left, &complete-word, &complete-line,
-	  parentheses flashing) while data comes from the MUD.
-	* Fixed a line redrawing bug when inserting chars on terminals
-	  with VT100-like wrapglitch.
-	* Fixed SEGFAULT on #send, #emulate, #exe of a numeric expression.
-	* Fixed stupid SEGFAULT when cancelling an editing session.
-	* Fixed sending/receiving latin-1 '\377' (ASCII char 255) as IAC IAC
-	  to conform telnet protocol, both directly and inside MPI messages.
-	* Fixed matching #actions, #prompts and #marks on MUD data splitted
-	  into multiple fragments.
-	* Fixed line length calculation when receiving '\r' in the middle
-	  of a line.
-	* Fixed extra prompt redrawing in #option +compact mode.
-	* Added #option sendsize and #option autoclear.
-	  Changed default not to send window size upon connecting.
-	  (if the MUD asks it, the window size is sent anyway)
-	  Use #option +sendsize to automatically send it when you connect.
-	* Added command #rawsend.
-	* Removed bits of ANSI code giving problems
-	  with really picky non-ANSI compilers
-	  
-Changes from 1.2.0 to 1.2.1 (Massimiliano Ghilardi) 20 Nov 1998
-	* Fixed a typo in Makefile.
-	* Reversed order of saved #history lines.
-	* Fixed out-of-bound array accesses in tcp_find() and tcp_show()
-	  which could give SEGFAULT on #connect, #snoop and #zap.
-	* Fixed buggy loop in saving #history in definition file that could
-	  create a huge temporary file, filling the filesystem.
-	* Fixed sporadic SEGFAULT when hitting backspace and some other
-	  editing keys.
-	* Math operator `?' could freeze due to buggy code.
-	  Systems providing GNU memmem() didn't experience the problem
-	  as it was used instead of my replacement code.
-	* Enhanced support for terminals with VT100-like wrapglitch:
-	  on them, the rightmost character of every line is used too.
-	* Fixed wrapping in #printing strings containing ASCII chars > 127
-	  when #option wrap is on.
-	* Fixed incorrect drawing of prompt and command line under some
-	  circumstances.
-	* Fixed wrong wrapping of lines immediately after the prompt
-	  in #option +wrap mode.
-	* Removed extra newlines sent after each line in `#send <filename'
-	  and `send !command'.
-	* Fixed a few off-by-one errors causing corruption in #movie/#capture
-	  and (reprint) buffers.
-	* Powwow now discards all \r received immediately before or after \n,
-	  to avoid troubles when strange data comes just before the prompt.
-	* Changed MPI key to `unsigned int' because MUME uses a 32 bit
-	  unsigned value for it.
-	* Cleaned up remote file editing not to leave stale files in /tmp.
-	* Cleaned up multiple connections support:
-	  Fixed spurious `#too many open connections' errors.
-	  Fixed prompt drawing glitches when getting data from subsidiary
-	  connections.
-
-Changes from 1.1.7 to 1.2.0 (Massimiliano Ghilardi) 05 Oct 1998
-	* Copyright change. Powwow is now GPL-ed.
-	* Version number bump. I hope there aren't many bugs left.
-	  If you are coming from 1.0.x versions, read this file and powwow.doc
-	  carefully, many things have changed!
-	* Fixed double-newline printing after each line if #option +wrap
-	  was set.
-	* Suppressed useless reprinting of files sent back to MUD
-	  using MUME remote editing protocol.
-	* Updated a few details in docs.
-	* Some old compilers choked on bits of ANSI code. Fixed.
-	* Fixed extra newline after prompt in #movie and #capture
-	  when #setvar buffer is not zero.
-	* Fixed extra \r at beginning of a line under rare circumstances.
-	* #delim now unescapes the custom delimeters.
-	* Added missing close() when remote host closes connection.
-	* Rewrote the code to merge lines received in two (or more) fragments.
-	* Added `#help warranty' and `#help copyright' to conform GPL :-/
-
-Changes from 1.1.6 to 1.1.7 (Massimiliano Ghilardi) 15 Sep 1998
-	* Changed meaning and effect of #prompt and #isprompt.
-	  If you used them, re-read their docs in powwow.doc!
-	* Alias names containing spaces are now rejected too.
-	  Relaxed rules a little, unbalanced () {} or ""
-	  now just print a warning instead of causing an error.
-	* Added #option reprint.
-	* Old #prompts were not removed on #load. fixed.
-	* Fixed SEGFAULT when chaining very long strings:
-	  #("foo..." + "bar...")
-	* Fixed small compiling problems on some platforms.
-	* Fixed an off-by-one error in math operator >:
-	* Fixed math operator `=' bug on copying empty strings.
-	* Fixed a crashy bug in #reset var.
-	* Fixed some quirks in unescaping strings:
-	  ending backslashes caused SEGFAULT,
-	  sequences like \\\``` were unescaped incorrectly.
-	* Fixed incorrect code in #mark and #action that
-	  mismatched patterns containing two or more wildcards.
-	
-Changes from 1.1.5 to 1.1.6 (Massimiliano Ghilardi) 03 Sep 1998
-	* Added circular backbuffer for #capture and #movie.
-	  Can be enabled/disabled/resized with #setvar buffer.
-	* Sanitized aliases: powwow now rejects alias names containing
-	  unbalanced special chars ""(){} . Example:
-	  #alias (=#print   is illegal, while
-	  #alias "("=#print is ok.
-	  #alias {}=#print  is ok,
-	  #alias \\{=#print is ok too as it matches \{ and _not_ {
-	* Removed a redundant alias unescaping. If #alias foo=\\bar
-	  then `foo' now sends `\bar' instead of `bar'.
-	* Fixed a compatibility problem when reading #binds of new savefiles
-	  using old versions of powwow.
-	* Fixed some problems with #var on numbered variables.
-	* Fixed #internal error, selflookup_sortednode() failed!
-	  that affected 1.1.5
-	* Fixed SEGFAULT upon #exe \; (introduced in 1.1.5).
-	* When getting data from the MUD after a prompt which set #isprompt
-	  the data is now printed as a separate line even if it doesn't start
-	  with a newline. Helps turning things like
-	      * HP:Fine>You hit the wolf's head hard.
-	  into
-	      * HP:Fine>
-	      You hit the wolf's head hard.
-	  Anyway, such data has _always_ been considered separate
-	  from the prompt if it set #isprompt, i.e. #action patterns like
-	  "^You hit the wolf" already worked in the above case.
-	  
-Changes from 1.1.4 to 1.1.5 (Massimiliano Ghilardi) 30 Aug 1998
-	* Massive code cleanup.
-	* Finished removing size limits on strings, text lines and variables.
-	* Renamed `#settimer' as `#setvar timer' and `#lines' as `#setvar lines'
-	  Added `#setvar mem' to set/edit/remove length limit on text/strings.
-	* Powwow now stops command execution after any error.
-	* #key now works also with editing keys.
-	* Added #keyedit command. "#keyedit &prev-line" runs
-	  the editing function `&prev-line' and so on.
-	* Added "&insert-string <string>" editing function.
-	* Added #mark ^pattern, which matches only at line start.
-	* Decreased CPU usage when/after a lot of variables, aliases or marks
-	  are created.
-	* Added `*' and `*=' math operator for strings.
-	* Fixed math operators ^^=, ||= and &&= to always return 0 or 1.
-	* Fixed SEGFAULT when creating more than 100 variables.
-	  (bug introduced in 1.1.0)
-	* Fixed SEGFAULT when realloc()ing very big strings.
-	* Fixed memory leaks when running out of memory.
-	* Fixed escaping/printing of nasty strings like
-	  backslash + control char.
-	* Fixed some redrawing glitches on very long input lines.
-	  Input lines bigger than the whole window are still not drawn
-	  correctly. Same problem on prompts longer than a line.
-	* Fixed #prompts to fully work also on prompts received inside
-	  a set of newline-terminated lines.
-	* Documented #prompt, #capture and #movie to work only for
-	  the main MUD connection
-	  
-Changes from 1.1.3 to 1.1.4 (Massimiliano Ghilardi) 23 Jul 1998
-	* Renamed `movie_play' to `movie'. Will do the replay if invoked as
-	  `movie_play' and will convert to ASCII if invoked as `movie2ascii'
-	* Fixed a 1.1.1 bug that could cause a lot of missed binds.
-	* Finished adding ANSI prototypes. Renamed some files and remixed
-	  some code in the process.
-	* Removed -DUSE_TERMIO. If you used it, no problem.
-	  If you didn't use it, you must now add -DUSE_SGTTY.
-	* Fixed a few compiling problems on OSF1 and other systems
-	  with really annoying compilers.
-	* Fixed missing sig_oneshot on systems without SA_ONESHOT
-	* Fixed input of chars with high bit set (again).
-	
-Changes from 1.1.2 to 1.1.3 (Massimiliano Ghilardi) 21 Jul 1998
-	* Variable names are now expressions too. This means that
-	  @("foo"+"bar") is the variable @foobar.
-	* Added `just in time' substitution: ${varname} @{varname} and #{expr}
-	  Not yet implemented for regexp patterns, sorry.
-	  This introduces a subtle incompatibility with older versions,
-	  as now also text coming from $n substitution gets unescaped.
-	  Sorry again. (see powwow.doc for details).
-	* #action and #prompt did not work when using an expression
-	  as pattern. Now fixed.
-	* Fixed small bug in anonymous actions. Someone still using them?
-	* powwow_help renamed powwow.help
-	* Fixed a bug in #alias: $1..$9 all contained the first word ($1)
-	* Fixed math operators . : .? :? .< .> <. >. :< :> <: >: which
-	  segfaulted on empty strings (bug introduced in 1.1.0)
-	* Made SIGINT signal handler non-permanent to allow interrupting
-	  system calls like connect(). Partially reverses the change in 0.9.3
-	* Undone a change Gustav made in 0.9.3: now #connect with no args
-	  always lists the open connections. To open a new connection you must
-	  give at least one argument, for example #connect main.
-	* Changed edit function &redraw-line not to clear prompt.
-	  Use &redraw-line-noprompt to get the old behaviour.
-	* Added #movie command to record all output from the MUD
-	  and local commands to a file, adding timestamps to allow replay
-	  at correct speed. Also added `movie_play' standalone program
-	  to actually do the replay.
-
-Changes from 1.1.1 to 1.1.2 (Massimiliano Ghilardi) 16 Jun 1998
-	* The wildcard `$' now correctly matches single words only
-	  both in #actions and in #marks.
-	  It was (again!) matching also multiple words like `&'
-	* Fixed up attr and noattr math operators, which broke in 1.1.0
-	* Added workaround for buggy terminals which create empty lines with 
-	  coloured background when using #hilite <whatever> on <colour>.
-	  Must compile with -DBUG_ANSI to enable it.
-
-Changes from 1.1.0 to 1.1.1 (Massimiliano Ghilardi) 11 Jun 1998
-	* Added some changes from 1.0.1 that didn't go in 1.1.0.
-	  The 1.0.x and the 1.1.x trees are indipendent...
-	* Wrote a memmem() replacement for systems that don't have it.
-	* Decreased CPU usage when receiving lots of text from the terminal
-	  (for example using cut-n-paste)
-	* Continued adding ANSI prototypes.	
-
-Changes from 1.0.0 to 1.1.0 (Massimiliano Ghilardi) 20 May 1998
-	* Splitted 1.0.x and 1.1.x source trees.
-	* Started adding ANSI function prototypes.
-	  Old K&R compilers still work.
-	* Removed all size limits in all strings, text lines and variables.
-	  Also allowed '\0' (ASCII zero) in strings.
-	  It was a _huge_ task! Probably messed up all and everything.
-	* Side effect of the above: lines of arbitrary length received from
-	  the MUD should now work perfectly (at least as long as you have
-	  enough memory)
-
-Changes from 1.0.0 to 1.0.1 (Massimiliano Ghilardi) 18 May 1998
-	* Changed name of some files (Changelog, Hacking, Compile.how,
-	  Config.demo)
-	* Fixed #capture and #record to save text from main connection only.
-	* Fixed a buffer overrun in $last_line when receiving lines longer
-	  than 1024 chars. Hopefully lines up to 4095 chars will now work.
-	* Fixed message "Creating %s" when creating a new definition file.
-	* Added `catrw' standalone mini-program for splitting powwow output
-	  in multiple windows (quick tutorial in powwow.doc, section #write)
-	* Added #rebindall and #rebindALL
-
-Changes from 0.9.9 to 1.0.0 (Massimiliano Ghilardi) 13 May 1998
-        * Disabled NAGLE for tcp connections (set TCP_NODELAY option)
-	  which should hopefully increase performance during lossy conditions
-	  (idea and code contributed by Finne Arne Gangstad)
-	* Cleaned up error handling. Powwow tries really hard to report
-	  any system call error, quitting only when there is really no hope.
-	  Anyway, if you get a '#system call error' message, you should
-	  seriously consider quitting as soon as possible since either
-	  the connection is messed up or your system is running
-	  out of resources.
-	* Removed extra newline after prompt bug when in #option -compact mode,
-	  introduced in 0.9.7
-	* Fixed $last_line to contain last non-empty line from the MUD.
-	* Updated config.demo with definitions for time-inside-prompt
-	  and other things.
-
-Changes from 0.9.8 to 0.9.9 (Massimiliano Ghilardi) 12 May 1998
- 	* Changed rx.h to regex.h in includes
-	* Fixed behaviour on prompts and lines received in multiple packets:
-	  0.9.7 and 0.9.8 sometimes print garbage.
-	* Added some flush()es in the code to cope with the new
-	  terminal I/O buffering.
-
-Changes from 0.9.7 to 0.9.8 (Massimiliano Ghilardi) 11 May 1998
-	* Fixed compile problems on AIX (got out of sync).
-	* Fixed a stupid bug that caused all actions to be regexp
-	  (introduced in 0.9.7)
-	* Introduced a more efficient terminal I/O buffering.
-
-Changes from 0.9.6 to 0.9.7 (Massimiliano Ghilardi) 11 May 1998
-	* Increased stability when receiving extremely long lines (>1024 bytes)
-	  The fix is only partial, powwow can still crash on lines slightly
-	  shorter than 4096 bytes when a lot of #marks are used.
-	* Cleaned up the names of various #defines
-	  In particular, USETERMIO is now USE_TERMIO and
-	  TELNETBUG is now BUG_TELNET
-	* Added #option autoprint, to automatically print lines matched
-	  by #actions.
-	* Added #spawn command.
-	* Added #prompt command. Just like #action, but matches both on
-	  prompts and on normal text.
-	* #actions now work differently on prompts:
-	  prompts are not matched immediately against #actions,
-	  but only after a \n arrives from the MUD, just in case they are
-	  actually normal lines received in multiple packets and not prompts.
-	  
-	  Thanks to the this change, powwow behaves better on lines received
-	  in two (or more) packets.
-	  See the file powwow.doc, section `#prompt' for the gory details.
-
-Changes from 0.9.5 to 0.9.6
-                   (Gustav Hållberg, Massimiliano Ghilardi) 16 Oct 1997
-	* Fixed a nasty security hole in MPI messages
-	* Fixed handling of \; at the end of a command
-	* Fixed some other problems:
-	  short messages from MUD could interfere with remote editing,
-	  #bind escape sequences containing \0 were incorrectly printed/saved
-
-Changes from 0.9.4 to 0.9.5
-                   (Gustav Hållberg, Massimiliano Ghilardi) 18 Sep 1997
-	* Continued code cleanup
-	* Allowed aliases starting with `#'
-	* Removed #speedwalk, #info, #echo, #keyecho, #compact and #debug
-	  and turned them into #options: `#option echo' and so on.
-	  For compatibility, `#echo' is aliased to `#option echo' and so on.
-	* Fixed a dangerous bug making cursor jump to start of typed text
-	  when receiving a line that wraps. The bug appeared in 0.9.4,
-	  so blame Gustav ;)
-	* Fixed an old bug making powwow sometimes miss a bind
-        * Made the command from a bound key appear with `#hilite' setting
-        * Made a DEFAULT_HELP_DIR define in powwow.c
-	* Changed to from ' ' to ` ' in some messages
-
-Changes from 0.9.3 to 0.9.4 (Massimiliano Ghilardi) 04 Sep 1997
-	* Included all the huge changes made by Gustav Hållberg:
-	  I really have no time to double-check them all.
-	  If something works in 0.9.2 but is broken in 0.9.4,
-	  you know who to bother :)
-	* Small esthetic changes in the source, no effects on executable
-	* Changed identifier for regexp #actions from ']' to '%'
-
-Changes from 0.9.2 to 0.9.3 (Gustav Hållberg) 11 Aug 1997
-	* Fixed so packets ending with \r*\n\r* set promptstr to ""
-	* Made all signal handlers permanent (sig_permanent)
-	* Debugged and reinstalled #option (it was commented out for some
-	  obscure reason (Massimiliano: I never finished it...)),
-	  allowing storage of command history and word 
-	  completions in the savefile. Added the 'exit' option to allow
-	  powwow to autoexit when the last connection closes
-	* #echo, #info, #wrap and #debug now get saved in the savefile
-	* Made repetitive use of &complete-word and &complete-line cycle 
-	  through possible completions
-	* Made a memory-safe strdup (called str_dup)
-	* When starting a child viewer/editor, that process' TITLE 
-	  environment variable is set to something appropriate (?)
-	* Regular expressions (Extended POSIX regexp)
-	  available for actions; uses GNU rx.
-	* Actions with label "" forbidden
-	* Added the #delim command to change word delimeter mode
-	* Whenever main_conn changes permanently, linemode is set to 0 and
-	  promptstr to ""
-	* Fixed a crashy bug in the >: operator
-	* Fixed the notorious extra-space-on-insert bug (both 'ic' and 'im'
-	  shall NOT be sent if you want to insert something) and a VT100
-	  mode bug while I was feeling creative
-	* Made the local editing protocol respect prompts (i.e. they get
-	  rewritten after protocol messages are shown). After texts are sent
-	  back to the mud, the output buffer is flushed (no more pressing
-	  ENTER after you've stopped editing!)
-	* Fixed a few bugs in #mark; pattern "&" doesn't crash anymore.
-	  Patterns with consecutive wildcards never worked, so I forbade them.
-	  It could be implemented, but I hardly think it's worth it
-	* Added the ANSIBUG compiler directive to fix the bug in some terms
-	  that show new lines in the current output attrib (screws #mark e.g.)
-	* Made '#connect' without parameters try to open a connection
-	  titled 'main' to 'hostname' (if specified) if no conns are open.
-	  The initstr from #init will be used in this case
-	* Added &transpose-words, &upcase-word and &downcase-word (defaults
-	  to M-t, M-u and M-l). Repetition of the latter two changes case
-	  of the whole line
-	* Changed default key names to be more emacs-like (C-b, Ret etc)
-	* Made #host get written to the savefile iff *hostname != 0, and 
-	  if powwow is started as 'powwow filename', without any #host in
-	  the file, #init is ran immediately
-	* Fixed a bug in cmd_print() that didn't cope with $0 not being set
-	* Allowed \0 to be part of a bound key's escape sequence. New format
-	  for #bind allows octal \012 be part of the string representation
-	  of the esc seq (chars with high bit set get saved in octal now)
-	* Made permanent variables $last_line and $prompt
-	* Made "#var" without arguments list all defined named variables
-
-Changes from 0.9.1 to 0.9.2 (Massimiliano Ghilardi) 04 Jun 1997
-	* Added #keyecho command toggle echo of bound keys.
-	  Previously, this was controlled by the generic #echo command.
-	* CTRL-C can now safely interrupt blocking commands like
-	  #connect and #bind.
-	* POWWOWDIR is now used correctly in all cases:
-	  not only when starting powwow with a filename but also when using
-	  #load, #save or #file
-	* Changed #file syntax. Now you need = before the save-file.
-	  Putting = alone undefines the save-file and disables autosave
-	  when you quit.
-	* Cleaned up naming conventions: 'session' means editing session
-	  while 'connection' means remote host connection.
-	* Fixed handling of 8 bit chars typed from keyboard
-	* Fixed '#reset bind' which was not reloading cursor binds
-	* Fixed remote host name spelling in files generated by #save.
-	* Fixed a bug that caused powwow to crash when failing to
-	  connect to a mud.
-
-Changes from 0.9.0 to 0.9.1 (Massimiliano Ghilardi) 31 Apr 1997
-	* New connections opened with #connect are set as main connection.
-	  You will have to switch back manually if you need it.
-	* Cleaned up multiple connection support. Better error handling.
-	* Cleaned up TELNETBUG support. I did not use it recently,
-	  and was out of sync.
-	* Enhanced #bind syntax: now you can specify control codes
-	  sent by your keyboard directly from the command line.
-	  As a side effect, #exe <file now works also on files created
-	  with #save
-	* Added #rebind command. Changes the control codes associated
-	  to a key binding without changing its name or its effect.
-	* Added #quit command.
-
-Changes from 0.8.6 to 0.9.0 (Massimiliano Ghilardi) 29 Apr 1997
-        * Added FreeBSD support in make_it (thanks to Jaako Knuutila)
-        * Cleaned up terminal interface.
-	* #save and #load now accept a filename as argument
-	* Handle SIGQUIT as SIGINT: use to stop long or infinite loops
-	* Now can switch main connection on the fly with ##<connection-name>
-	* Allow powwow #commands also on subsidiary connections
-
-Changes from 0.8.5 to 0.8.6 (Paolo Gatti, Massimiliano Ghilardi) 28 Apr 1997
-        * Finally and definitively changed the name to powwow.
-	  Previously, sometimes the program was referred to as pow-wow
-	  and sometimes as powwow, generating confusion.
-        * Partial port of powwow to AmigaDOS. Incomplete, will NOT compile.
-	  Paolo abandoned the project, so maybe it will just never compile.
-	* Fixed a bug causing extra new-lines on screen when powwow received
-	  strange data sequences like ASCII codes 10 13
-	  (on DOS, new-line is 13 10, while on UN*X is 10 only)
-        * Fixed a bug in #mark not matching correctly the wildcard $
-        * Powwow crashed #loading files containing empty lines. Fixed
-
-Changes from 0.8.4 to 0.8.5 (Massimiliano Ghilardi)
-	* Fixed a bug introduced by updating files from cancan 2.6.0b sources
-	  (happened in version 0.8.3): powwow was sendind TWO new-line chars
-	  instead of one immediately after every password.
-
-Changes from 0.8.3 to 0.8.4 (Massimiliano Ghilardi)
-	* Fixed (I hope definitively) an ancient bug:
-	  some lines were sometimes printed twice or not printed at all.
-	  It is still the bug that appeared in version 0.4...
-	  The bug was almost fixed in version 0.8b but reintroduced in 0.8.3
-
-Changes from 0.8b to 0.8.3 (Massimiliano Ghilardi)
-	* Slightly changed version numbering (0.8.3 instead of 0.8c)
-	* #save and #load are now safe even in case of errors
-	  (example: `disk full')
-	* hitting a #bind-ed key now echoes the corresponding command
-	  only if #echo is on
-        * updated term.c (terminal handling code) and tel.c (telnet code)
-	  with files from cancan 2.6.0b (yes, I shamelessly copied them)
-	  No external changes anyway (unless I introduced some bugs)
-          note: beam.c NOT updated/copied
-        * 'follow' standalone mini-program added (see README.follow)
-        * #key is now explicitly stated not to support editing keys.
-	  They cannot be added cleanly without rewriting the line-editing code
-	  from scratch ('#key up' and '#key return' give the biggest problems)
-	  and I don't have the time for that right now
-        * blink attribute added
-        * Now can use multiple attributes in #mark, #hilite, #color
-	  example: #mark *An Orc*=inverse bold blue on red
-	  Note: bold, blink, underline and inverse must appear BEFORE colors
-	* fixed some bugs:
-	* changed "VERSION" to "POWWOW_VERSION" in powwow.c.
-	  It seems some compilers use VERSION for internal purposes...
-	* #wrap mode was discarding lines containing only escape sequences
-	  (example: color codes coming from the MUD)
-        * #hilite was restoring hilight attributes after EVERY line
-	  coming from the MUD
-	* self-recursive aliases were causing crash after 100 loops instead
-	  of trapping error and reporting '#error: stack overflow'
-	  (not always, and not on all OS). Now they are completely safe.
-	  Note: they still eat 1MB of memory (10K per loop - released
-	  immediately after)
-
-Changes from 0.8a to 0.8b (Massimiliano Ghilardi)
-	* hexadecimal numbers added (and in any other base)
-	  can be used only from calculator, prefix is #
-	* '#write' command added
-	* fixed a bug with #nice affecting #load
-	  now #load places actions/marks in memory in the same order as
-	  config file, indipendently from #nice value.
-	  Also, default #nice changes from 1 (top) to 0 (bottom)
-	* fixed a bug in #save that sometimes caused crashes and destroyed
-	  config file
-	* now word completion (issued with TAB key) checks
-	  word completion list _before_ built-in commands
-
-Changes from 0.8 to 0.8a (Massimiliano Ghilardi)
-	* remind me NEVER to work on Sunday, because I filled version 0.8 with
-	  these bugs (now fixed):
-	  - some debugging stuff was not deleted from official version
-	  - deleting a named variable could cause a crash
-	  - creating a named variable was giving a message even while reading
-	    a definition file
-	  - #settimer was not working due to a change in version 0.8
-	  - forgot to say that #map variable was added
-	* #rand, #map and #timer variables renamed rand, map and timer
-	  (removed the #) - sorry for the change but it was necessary.
-	* removed limit of 50 named variables of each kind (numeric and string)
-	  now the only limit is the memory available
-
-Changes from 0.7b to 0.8 (Massimiliano Ghilardi)
-	* #mark now accepts wildcards ($ for a single word, & for a string)
-	* named variables are now supported
-	* #assign renamed #var (I never liked the name 'assign' ...)
-	  also, #var can be used to delete variables from memory
-	* #nice command added. It sets/shows priority of new actions/marks
-
-Changes from 0.7a to 0.7b (Finn Arne Gangstad)
-        * make_it now also works for sunos 5.x, irix 5.x and hpux 9.x
-
-Changes from 0.7 to 0.7a (Massimiliano Ghilardi)
-	* fixed a _HUGE_ hole in security: $n in actions was matching also ;
-	  (but not spaces) so robotic actions gave a chance to other players
-	  to force you (*AAARGH*)
-	* startup changed: now powwow does not clear screen when executed,
-	  but jumps to the end of screen (this avoids mess in the first lines
-	  you get from the mud)
-
-Changes from 0.6d to 0.7 (Massimiliano Ghilardi)
-	* finally fixed the unpleasant bug of auto-wrap making confusion when
-	  receiving lines that contain escape sequences
-	  (the fix in 0.6d was far from satisfactory)
-	* high-intensity colours added (for the terminals that support them)
-	* #assign can be used to put the contents of a variable on input line
-	* number of global variables raised to 50, max lenght of string
-	  variables raised to 512 bytes
-	* #settimer command added, '#time' variable changed into '#timer'
-	* fixed a bug: math operator >= was wrong, worked as <=
-
-Changes from 0.6c to 0.6d (Massimiliano Ghilardi)
-	* break key now is also used to stop command-parsing. Useful to stop
-	  long or infinite loops without exiting from powwow.
-	* #stop command added. It disables all active delayed commands.
-	* #mark now works also with prompts (was not implemented before)
-	* fixed an ancient bug with #action not working on lines splitted into
-	  multiple data packets by telnet.
-	* fixed two other ancient bugs:
-	  #mark not working on auto-wrapped words
-	  and auto-wrap making confusion when receiving lines that contain
-	  escape sequences (only partially fixed to be honest)
-	* Now the unescaping is performed ALSO on quoted strings, when powwow
-	  evaluates them. Thus there might be to update your definition file
-	  if it contains escapes placed in strings.
-
-Changes from 0.6b to 0.6c (Massimiliano Ghilardi)
-	* If you have problems with #rand, random() and srandom() (typically
-	  your compiler is unable to find the functions) you can define
-	  NO_RANDOM at compile time. (temporary solution)
-	* Now also editing keys can be redefined
-	* #assign command added (same syntax of #print, #send and #exe)
-	* Now you can specify start and end line of a file or output of Bourne
-	  shell command when using #print, #send, #exe, #emulate or #assign
-	* #debug command added (try it in test mode...)
-	* Now #echo, #info, #speedwalk and #debug also accept 'on' or 'off'
-
-Changes from 0.6 to 0.6b (Massimiliano Ghilardi)
-	* #emulate command added (same syntax of #print, #send and #exe)
-	* now also prompts can be intercepted by #actions
-	  (but cannot be 'gagged')
-	* powwow can run in test-mode without being connected to a MUD
-
-Changes from 0.5 to 0.6 (Massimiliano Ghilardi)
-	* more debug work
-	* #exe, #send and #print extended to use shell commands and files
-	  Also, #send replaces #read
-	* #time variable added
-	* #rand function added
-	* #connect now supports a different remote host for each connection
-	  (i.e. you can now play on different MUDs with the same invocation
-	  of powwow)
-
-	Ideas coming from Cancan 2.5.1c and implemented on powwow 0.6:
-
-	* output to the remote host is buffered up and sent all at once in the
-	  main loop, to reduce the number of network packets. Long aliases
-	  might benefit from this, as would repeated commands (#10 buy bread).
-	* #help now works on commands. A help file is needed and provided.
-	* new command: #record, records lines you type in a file
-	* source changed so path for helpfile is taken from environment
-	  variable POWWOWHELP (if this variable is not defined, powwow looks
-	  in current directory)
-	* to print the message of the day, must define MOTDFILE in compiling
-	  with the name (and complete path) of the file containing the message
-	* Now compiles on BSD/386 as well, automatically detected by make_it
-
-Changes from 0.4 to 0.5 (Massimiliano Ghilardi)
-	* Heavy debug work, since 0.4 was an alpha version
-	  (it is not a good idea to place here the huge list of bugs fixed...)
-	* added #history to list/execute commands in history
-	  Note: #history commands are not placed in history...
-	* now internal commands can be abbreviated, for example #al can be used
-	  istead of #alias. However, internal commands are still completed
-	  using TAB
-
-Changes from Cancan 2.5.0b to powwow 0.4 (Massimiliano Ghilardi)
-	* Inline calculator, with both global and local variables, and C-like
-	  syntax
-	* added commands #(), #print, #send, #exe to use inline calculator
-	* added commands #if-#else, #for and #while.
-	* added #key, #save, #load, #save, #lines, #info, #echo, #compact, 
-	  #net, #clock, #time
-	* added #in and #at to define/edit delayed commands
-	* #mark and all attrib-related commands now accept also the attribute
-	  'none'
-	* #marks and #actions now are not automatically sorted (to sort them,
-	  define SORT in compiling). #aliases and #binds instead are always
-	  sorted.
-	* #aliases can be self-recursive now (it is potentially dangerous,
-	  powwow will not enter a very long - but not infinite - loop)
-	* Must not escape ';' anymore to place multiple commands in #alias,
-	  #action or #bind. Instead, multiple commands must be surrounded by
-	  braces, { and }
-	* #action changed syntax (not need double quotes anymore, but need one
-	  of > < + - = before label) See powwow.doc for details
-	  Lines matched with #action are not printed on screen automatically,
-	  must use a #print to echo them
-	* #gag is suppressed (not needed anymore), and #add is now a command
-	* Escaping technique changed. Now unescaping '\\\#' gives '\\#' (i.e.
-	  remove one \ each time), and you can also escape \, in this way:
-	  \` gives \ alone, \`` gives \` and so on. So for example, if you
-	  want to place a \ at the end of an #action pattern, you must write
-	  \` , to avoid escaping the = after the pattern
-	* Some bugs of Cancan fixed (small things, expecially wrapping)
-
-Changes from 2.5.0a to 2.5.0b (Finn Arne Gangstad)
-	* Fixed bug with client aborting when window was resized.
-
-Changes from 2.5.0 to 2.5.0a (Finn Arne Gangstad)
-	* Various tweaks to make it compile on most systems.
-
-Changes from 2.4.4 to 2.5.0 (Mattias Engdegård)
-	* the length of the prompt is now correctly calculated
-	  even if it contains escape sequences (for muds with coloured prompt).
-	* built-in commands are always completed with tab and aren't stored in
-	  the word list
-	* #hilite and #mark now accept general attributes: ansi colours and
-	  bold, underline, inverse.
-	* the #action command has changed syntax; now double quotes are
-	  required around the pattern, but they can be named. Actions can be
-	  turned on and off.
-	* the keydefs list contains all keyboard bindings. The #bind command
-	  can define new keys.
-	* the #alias, #action, #bind and #mark commands can now put a
-	  definition line in the input buffer for easy editing.
-	  The keys M-p and M-n are no longer used.
-	* some new files, new source module discipline with external
-	  declarations only in header files.
-	* added the file `Hacking' with some advice.
-	* mapping functions cleaned up. #map now displays ssss as 4s.
-	* the definition file is tagged with a file version, to make it easier
-	  to recognize older save formats.
-	* cancan now displays a motd file whose location is set at compile
-	  time (see Makefile).
-	* define TELNETBUG to work around an NCSA telnet 2.2 colour bug.
-	  #stdcolour can be used to set the background colour if TELNETBUG is
-	  defined.
-
-Changes from 2.4.3 to 2.4.4 (David Gay)
-	* telnet window size option supported
-
-Changes from 2.4.2 to 2.4.3
-        * added term support
-	* added #hilite to hilite user entered text
-	* added #mark and #unmark to mark special keywords...
-	* changed #identify to allow it to send alias' or commands to the
-	  mud when beginning/ending an editing session.
-	* changes the Makefile a bit to support termcancan
-	
-Changes from 2.4.1 to 2.4.2
-	* Added multiple-session support with following # commands:
-	  '#connect', '#zap', '#snoop', '##'
-	* Added numeric keypad movement, keypad sends commands
-	  n,e,s,w,u,d and exits.. (not on all systems)
-	* Easier editing of actions with meta-p and meta-n (not on all systems)
-	* Changed the 'make_it' script a bit, so that it echoes the make
-	  command it executes.
-
-Changes from 2.4.1 to 2.4.1b
-	* Improved modularity of source, new files cmd.c, cmd.h
-
-Changes from 2.4.0 to 2.4.1
-	* Changed & in actions to match a single word for backward
-	  compatibility.  &0..&9 still match multi-worded text.
-	* Now compiles on HP-UX (at least HP-UX 9.01A )
-	* Included a 'make_it' script that automatically compiles cancan for
-	  Linux, IRIX, AIX, ULTRIX, DolphinOS, SunOS and HP-UX sytems.
-
-Changes from 2.3.6 to 2.4.0
-	* Extended param substitution for & to &0..&9.
-	* Added '&&' syntax for delayed param substitution.

-	* Added '#speedwalk' to toggle speedwalk on and off.
-	* Added '#map' with automapping.
-	* Added '#retrace' to retrace steps.

-	  compiled with -DNOSORT.
-	* Added compile option -DNOSHELL to remove '#!' shell escape function.
-
-Changes from Cancan 2.3.5 to 2.3.6
-	* Fixed a bug with MUME's spinning delay bars and word wrap.
-	* & can now be escaped. This allows for aliases that create aliases,
-	  and other things.
-	* Added this change log (not too early)
-	* Checks the window size after being suspended, in case it was
-	  changed.
-	* Lines longer than screen width because of invisible spaces and/or
-	  trailing CR:s are not unnecessarily wrapped.
