Subject: Further cleanups and bugfixes
X-Git-Tag: v1.4.0-rc1~251
X-Git-Url: http://git.pk910.de/?a=commitdiff_plain;h=aade06878c014cae4f34d5ab1e63789faf51c6a2;p=srvx.git

Further cleanups and bugfixes

* Remove "TODO: reimplement" comment in chanserv.c, since all the
functions were already reimplemented.

* Make "/msg ChanServ huggle" work again.

* Fix error messages when bad target names given to say and emote.

* If we get a MODE change affecting a user who somehow quit already,
just ignore it.

* Add debugging checks for mod_chanmode argument counts.
