TODO/bugs In SILC Client Library
================================
+ o Someone changing nickname on the channel from nick to Nick will cause
+ that the new nick becomes Nick@host, because the old nick is not
+ removed from the cache before adding the new one. This is because
+ of the way NICK_CHANGE notify is handled. This should be fixed so
+ that if the old nick is to be removed the new nick will *replace*
+ the old one.
+
o JOIN command's argument handling is buggy. See the XXX in the code.
