  returns.
* Added sets FLOOD_RATE_PER and FLOOD_MASKUSER.
* Altered the "accept" mode of the dcc_raw and dcc_connect hooks to refer
  to the local port instead of the remote port.
* Added a "-closein %proc" switch to /exec.
* Altered the arg list mode of /alias to use extractw instead of next_arg.
* Added the documented "words" argument to the above.
* Tuned autoget, mudirc, tabkey.ce and commandqueues.
* Altered /pretend to not chop the string.
* Set about rewriting the flood detection and then decided that it's better
  off being a script.
* Moved the function macros to their own file (functions.h) and replaced
  all the copies that are strewn throughout the source with an #include.
  The exception is array.c which broke when I tried it.
* Moved the ctcp enquoting/dequoting functions to ircaux.c.
* Added some command/function ordering checks to funcs/regress, and a check
  for all the functions that are undocumented.
* Rewrote function chanmodetype() so that it doesn't have all those flakey
  buffering things.  Hopefully it's readable now.  The significant change
  is that if a mode character appears twice in CHANMODES, the first one is
  returned instead of the last.
* Added EPIC::call() in the perl routines and an equivalent under tcl.
  this is designed to call a $function() directly, but it isn't really that
  fast, so I might rip them out again.
* The /wait internals used to store a few other settings, which were taken
  out, so I put them back.
* Fixed a few problems with normalize_filename() around the place.
* Fixed a bug with /timer in which it would never show the timers after a
  callback.

* Remove /set suppress_server_motd which didn't really work anyways.
* Add function decls for bsd_arc4* to ircaux.c
* Always check (window->hold_mode || window->autohold) together!
* Unhold_window()s only if both hold_mode and autohold are off!
* unhold_window()s instead of doing scrollback_end for robustness.
* Attempt to recover from the "output is below bottom of window" bug, whine.

Ach.  Here goes nothing.
Major commit which does many things, but the most prominent of which
is the final integration of the scrollback buffer with the hold buffer.
This fixes several annoying "features" and introduces a small truckload
of new features which have been requested recently.  Please see the
KNOWNBUGS or UPDATES file for more info, since I don't want this message
to be ridiculously long.

New keybindings system coming through.  Details can be found in doc/keys
and in a few other places. :)
-wd

Update documentation prior to epic4-1.1.6 release
Add "HAVE_GETSERVBYNAME" check to configure stuff.
Remove /SET RANDOM_LOCAL_PORTS which has gone away.
Fix some layout issues with gailib.c and change two function names.
Fix comment issue with ircsig.c
Fix uninitialized variable issue with keys.c
Remove mention of /SET RANDOM_LOCAL_PORTS in network.c

Update copyright notices and copyright dates.

* Fix for an SSL problem where SSL fails to negotiate.  It will bail to
  non-encrytion in this case now.
* Fix for splitw() which is used by $uniq() and other functions where some
  of the elements could be null pointers due to its use of new_next arg.
  This would cause qsort() to coredump.  Switched to safe_new_next_arg
  which seems to have a performance penalty of about 4%.
* Added an "OTHER" flag to $stripcrap() and the mangle settings, which
  catches all characters that other flags don't.  It isn't included in
  the ALL flag.

DEATH TO MEMCPY()!
Also, make need_redraw 'volatile' since we alter it in a signal handler.

* Rolled the $getsets() and $getcommands() code into macros and added
  $getfunctions().
* Added a server_established hook.  This is called before anything is sent
  to the server, and it is intended that for ssl connections, stuff can be
  quoted and hooked in plain text until the hook returns, although, it is
  difficult to verify that this will actually work.
* Made it so that when all variables are erased, the low level array that
  contains the variables is erased.  This is intended to make it easier to
  profile the memory use.
* Copyright notice added to perl.c.
* Minor stuff for tabkey.ce.

* New STATUS_HALFOP setting which acts much the same way as STATUS_CHANOP.
* New function $getcommands() which acts much the same way as $getsets().
  The internals for these two functions probably need to be rolled together.
* Cleanups and minor updates to tabkey.ce.

Applied the SSL patch from ay-ar.

Details are in README.SSL.  This works well at this point, but there may
be teething problems.

The whole ROM_CHAR thing was an accident waiting to happen.  Removed.
Add /SET ALLOW_C1_CHARS to protect from the ascii char 128-159 attacks
upon XTerm and GNU Screen users.  Defaults to OFF.

Thanks go to crazyeddy and zinx for working on this in my absence.
Add /set rom_char (defaults to off) which determines whether ^R rom_char
sequences will be honored or dishonored by epic.  Dishonored sequences
are not removed; they are just mangled.  This will help you detect those
who might try to use this feature for less than noble purposes.

Re-set the ^R character to "mode 5" processing; it had been set to "mode 6"
as a stop-gap measure.

Resizable wserv support!  No, really!  Backported from epic5.
I have to go through term.c again and make sure there are no unintended
casualties of the merge.  We should also start testing the resize handlers
to make sure they're happy.  I don't promise they'll all work first time,
but this is a good place to start!

Add /set auto_rejoin_connect -- this controls whether epic will try to
rejoin your channels when you are disconnected from a server *AND EPIC
WOULD ORDINARILY TRY TO REJOIN YOUR CHANNELS*.  This has *ABSOLUTELY NO
EFFECT AT ALL* in those cases where epic has thrown away your channels
and has no intentions of rejoining them.  This is only a way for you to
reduce current functionality, there are no bugs fixed with this.

Translation table support.  I pulled this from ircII-2.8.2.  Re-added by
incessant requests from russian users.  This adds /set translation and
/set translation_path.  The translation path is not hardcoded into the binary,
it is $IRCLIB/translation, where IRCLIB is determined at runtime.  You can
of course always /set it to whatever you want.  I am not making the
translation tables available with epic.  They are available in zillions of
places, and i'll probably create a tarfile that contains them.

bugfix:  /stack push+pop of an unset /set will now restore it to its
original value, ie, unset.

* Miscelaneous 3cat updates.
* History expansion copies the history buffer verbatim now.
  * Bugfix:  /!0 would not retrieve the first command entered.
  * Bugfix:  Negative numbers not found would be display the
    incorrect number in the error message.  eg:  /!-4444
* Alterations to remove_trailing_spaces interface.
* $igetrmatches() was defined, but inaccessible.

Two things:
* Remove /set notify_handler which didn't do anything.
* Rewrite /lastlog so i understand how it works.
  Big new feature, -regex, to support regex searching on lastlog!
* Commit #75.
