Also fix up some return values and stuff to use bool (or void if nothing). I just did it whilst I was here. According to jilles, the return value used to signify whether or not the client had exited. This was error-prone and was fixed a long, long time ago, but the return value was left int for historical reasons. Since the return type is not used (and has no clear use case anyway), it's safe to just get rid of it.

|

|
|
* 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.
