Event assign_zero: Variable "(irc)->roomlist" assigned value 0.
278 irc->roomlist = NULL;

288 gaim_roomlist_room_add_field(irc->roomlist, room, args[1]);

'name can't be both "323" and "322" at the same time, so this will never happen'

In the 323 case, this saves us a strcmp() that we know is useless, and adding the return is consistent with the 321 block above.
