I don't know what these last few posts have to do with the paste problem but I have a comment anyway...
An IRCD does not allow you to send empty PRIVMSG's (several spaces with nothing else is concidered empty by the server). So why should a client like mirc even attempt to send a privmsg with an empty text token (the protocol rfc requires the token, its not optional, and spaces-only is never concidered a valid token since they are the delimiters)
It's the ircd's job to accept/reject messages. Not to mention many people run modified servers that allow all sorts of things. Mirc should not place such limitations and add unnecessary code. It should simply attempt to send what the user is trying to send. If the server accepts it, great. If not, oh well I guess.
