SERVICE, SERVLIST, and SQUERY are required by RFC 2812 (it states in
section 3 that "all commands described in this section MUST be implemented
by any server for this protocol." -- So we implement them without (much)
actual functionality ...
Dana Dahlstrom reported that IRC_WHO did not follow
RFC 2812, Section 3.6.1. Specifically:
- IRC_WHO did not send "G" flag instead if "H" if client was away
- did not search username/servername/hostname etc. if argument
was not a channel.
Fix all of the above and tidy things up a bit.
Also add IRC_WHO test script contributed by Dana.
- New configuration option "MaxNickLength" to specify the allowed maximum
length of user nick names. Note: must be unique in an IRC network!
- Enhanced the IRC+ protocol to support an enhanced "server handshake" and
enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD).
See doc/Protocol.txt for details.
