*
* Now, the old code roger wrote, would allow the KICK to
* go through. Thats quite legit, but lets weird things like
* KICKS by users who appear not to be chanopped happen,
* or even neater, they appear not to be on the channel.
* This fits every definition of a desync, doesn't it? ;-)
* So I will allow the KICK, otherwise, things are MUCH worse.
* But I will warn it as a possible desync.
