1.8.5p4

Version 1.8.5 patchlevel 4 -- Jan ??, 2013

Major changes:

The player_name_len @config option is now the maximum length of a player name, instead of the maximum length+1, because doing it that way was rather silly. You may wish to lower yours by 1 now to compensate.
Having unescaped commas in the final arg of a function call is now deprecated, and will eventually become illegal. Any existing code which does this will spam you with a warning until you change it.
The stack (%0-%9) can now hold up to 30 arguments, with the additional 20 available through v(10) to v(29). $-commands, @functions and many built-in commands and functions (such as ufun(), @mapsql, etc) now make use of these args.

@dolist now accepts /inline and related switches, like @switch does.
@teleport/list teleports a list of objects to a single destination.
@sockset and SOCKSET can now show/set PROMPT_NEWLINES.
@halt now takes a /noeval switch, and will always strip curly braces when run /noeval.
Added @mail/cstats, which shows the mail stats you see on connection.
Added a new switch for @command/add, /rsnoparse, which stops the rightside arguments (after the '=') from being evaluated. Also clarified the help to show that /noparse only affects leftside args.
WHO, DOING and SESSION now take wildcard patterns for names, as well as a prefix.

lpids()' second argument has been altered slightly, to allow you to list the pids for one specific object only.
The "player" field in pidinfo() has been renamed to "executor", for clarity. "player" still works for backwards compatability.
stringsecs() can now handle the additional time periods that etime() can return (years, weeks).
colors(..., name) is much more efficient.
alias(object,) clears object's @alias.
v(<integer>) is no longer the same as get(me/<integer>). Instead, it always the <integer>th stack entry.
It's now documented that replace() can alter multiple words at once.
Some terminfo() information can now be retrieved by mortals on other players' connections.
Added a new option to colors() to include ansi underline, invert and flash from the input in the output.
locate() takes a new flag, 's', which will only return objects controlled by the looker.

ansi() now accepts a space-separated list of color codes, with later groups overriding earlier ones. Allows you to specify basic ANSI codes after XTERM color codes.
Compiler warning fixed.
Help fixes.
The tables mapping color names and RGB values are now generated by a script in utils/.
Converting from named colors to the nearest xterm or ansi equivalent is much more efficient.
Converting from extended colors to ansi colors is smarter.
Email registration no longer pretends to work with really!old!addresses.
Better error reporting in logs and event hooks on failed email registration.
@decompile <exit> now reports the exit's source room.
You now only need to control an object to change its zone, or to use it as a zone. Previously, ownership was required.
The hardcode now always ANSIs a string (such as an object name or help topic), even if the enactor isn't set ANSI. Fixes puppets, etc.

%c contained the evaluated input (the same as %u), instead of the unevaluated input.
repeat() could write partial ANSI tags, causing buffer overflows.
dbcks didn't reset corrupt exit's source room.
lmath(and,) returned 1 instead of 0.
Mixing old-style ansi colors and xterm colors was broken.
Players who couldn't see xterm colors would sometimes get a highlighted foreground color by mistake.
colors(<old-style-ansi>, hex) and colors(*, 16color) were broken.
ANSI highlight would sometimes bleed when xterm colors were downgraded to the basic 16-color ANSI palette.
@entrances didn't correctly report the source of an exit.
Fix a crashbug in @command/delete.
Fix database corruption on @flag/add.

The Builder() macro, which is unused in Penn but exists for backwards compatability, used command_check_byname(), which spammed people who could not build with "Permission denied." errors. It is now spam-free.
