* Add stub code for a scrollback indicator in the future (rb twincest)
* Add stub code for a ucs32 input line in the future.
* Reformat all of the /set creation code in vars.c

up on the right-hand margin if there is text on the input line past that
side.

* Add $serverctl(READ_FILE filename) to add servers from a servers file.
* Add some preliminary code for sending a /msg to a logfile.
* Make scrollback_start/end use "scroll up/down 999,999 lines"
* This is for future consolidation of the scrollback code.

Revamped input line a little. Added indicator for text scrolled off the left
of our input line.

* Roll forward portability changes from epic4-2.10 (larne)
* This also includes term.h -> termx.h -- Make sure you rerun configure!

* Put 'sig.inc' in include rather than source to fix build for r/o srcdir

* Reorganize do_screens() in prep for future work

* Make /xecho -w -1 go to the current window, for compat with epic4 (rb Black)
* Make the /server list show the vhost you're using.
* /LOADing an executable file results in a warning and not an error.
* Fix input line so it doesn't display hidden contents after ^L (rb wjr)
* Add a $strptime() function, but I still need a strptime() compat version.
* Add $ignorectl(SUSPEND) and $ignorectl(UNSUSPEND) to turn off ignores.

* Add a new internal function prepare_display2() a reduced version of p_d().

* Fix window toplines so they extend the width of the screen like statusbars.

* $info(o) now includes 'r' for libarchive, and 'x' for iconv support
* Unconditinally unset GREP_OPTIONS in configure (rb Pegasus)

* Support /input "prompt" (args) {code}. See UPDATES. (rb kreca) (fusion)

* Fix BACKWARD_WORD or PREVIOUS_WORD or whatever it's called.

* Fix configure so --with-threaded-stdout pulls in -pthread
* Include some commented out code that I'm ruminating over for input line
* Create CURSOR_LEFT and CURSOR_RIGHT macros to avoid assigning LOGICAL_CURSOR
* Default xforms now don't need to be ordered, or have default refnums.

Remove u_* bsd-isms so we can compile with -ansi on linux.

* Fix crash for /parsekey type_text

* Add socks5p.h from epic4 so we can build with socks5 again.
* Remember, it's ./configure --with-socks5=/usr/local/lib
* Make update_input() take a screen as an argument, to update one screen only.
* Make /window create screen's input lines work again (rb kitambi)

Normalize the BUILT_IN_BINDING/BUILT_IN_KEYBINDING macros.

Move some functions out of input.c to places where they make more sense.
This makes it easier for me to re-org input.c.

Fix another minor bug.

* Fix warnings found by gcc4 and run make depend.
* Add check for -Wno-pointer-sign to configure; makes using gcc4 less painful.

* Fix null deref in set_input() via reset_line() via ^U (rb kitambi)

* Stage 2 -- start eliminating "optimizations", use update_input() for redraw

Stage 1 in a major overhaul of the input line handling code.
Caution -- road may be slippery when wet.  Many more changes to come.

* Never allow INPUT_PROMPT_LEN to be < 0.
* This fixes the damage from resizing to 1x1 and then back again.

* Fix replace_line, it wasn't moving the cursor before writing new contents.
* Fix a double SSL_free, from yesterday's fixes.
* Revamp the "THANKS" file, removing people who contributed to epic4 but
  not (yet) to epic5.  Hopefully this will spur some of them to contribute
  again to be added again. =)

Fix bug. doh!

* Sort of forget to re-implement /set cmdchars.  The / is the cmdchar.
* Try to optimize parse_statement() and next_statement() some.

* Constify get_*_alias(), so lookups can't modify the actual alias this way.
* Rename parse_command() to parse_statement().
* Create a next_statement() to figure out how long the next stmt is.

* Refactor parse_command and parse_statement to better define their roles.
* Push responsibility for expansion to parse_statement, someday, to cmds!

* Create a "/set data" type (VARIABLE) which is union of (int) and (char *).
* Expose VARIABLE and variable types in vars.h for others to use.
* Break init of /set's into two parts, one to malloc() the set data
* The second part is to init the default values once command line is done.
* Fix some warnings from --with-warns
* Fix all /set callbacks to accept a (void *)(VARIABLE *) variable

* Whack the /IRCNAME and /REALNAME variable -- use /SET REALNAME, eh!
* Hack up /xecho -x to bide my time until i whack all those /sets it uses.
* Don't call set_input_prompt() in main() any more, it's handled elsewhere.

* Fix provided scripts to add $* when necessary.
* Fix up Makefile, configure, et al, to use epic5/ directories.

* Add 'hold_mode' script, implements ircII-like /set hold_mode[_interval]
* /XEVAL -- ends eval option processing, like how /xecho does it.

Teach all the /set callbacks to take a (const void *).
This fixes a bad-c problem with /set!

Commit 556
* Change #define DEFAULT_CPU_SAVER_EVERY to 60, it needs not be 0.
* Create 'clock.c', to hold clock generation, system timers, cpu saver watchdog

* Garbage collect unused 'irc_path' global variable.
* Add --with-warns to configure to do FreeBSD "WARNS" like compiler checks
* Many hundreds of changes to improve the "quality of code" in epic, including:
* - Treat all literal strings as (const char *) and fix const correctness.
* - Mopping up all remaining const-correctness issues
* - Do not "launder" a (const char *) to a (char *) in string searches, (ala
    strchr) but rather return a ssize_t offset value.
* - Particular, MatchingBracket() returns (ssize_t) and not (char *).
* - Eliminate all "shadow" variable names by changing them to something else.
* - Eliminate most function decls that do not include a prototype list.
* - Add prototypes for all extern functions that are missing them.
* - Ensure most function pointers include a prototype list.
* - In term.c, most of those (char *)'s are really (const char *)'s.
* - Explicitly specify 'static' functions as 'static'
* - Ensure every function is either 'static' or has a prototype.
* - Eliminate (unsigned) < (signed) type comparisons.
* Hopefully you should not notice any changes!

Another merge.

* Fix bug that caused cursor to go wacky on screen < 32 columns.
* Fix 464 handler to only prompt for password if we're not registered yet.

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.

Fixed some style breakage, and some warnings.
-wd

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

Update copyright notices and copyright dates.

No functional changes, just removal of unecessary whitespace at the end
of lines.  From adm.

This is the new highlight/attribute renderer.  It is a "true renderer"
because it actually renders things to look like what you say.  No longer
does turning on some attributes (color) turn others off, nor does turning
some off (bold) turn others off.  Some things may break with this, please
let me know, or feel free to pitch in and fix them.

Zinx will be happy to know that i did NOT use the epic5 "prepare_display"
routine because he was right, i did totaly break it.  I used the epic4
prepare_display function but just made it aware of the new attribute stuff.
