Subject: CHANSERV: Clarified behaviour of chanflag +f and empty topics.
X-Git-Url: https://jfr.im/git/irc/quakenet/newserv.git/commitdiff_plain/5bc296cea412ea68e1b5c7b8abac87eae85d15ac

CHANSERV: Clarified behaviour of chanflag +f and empty topics.

+f will now enforce an empty topic on a channel.

Added CLEARTOPIC command to clear out the saved topic if that's what you
want to do.
