with messages this long deserve not to get the reply.
The problem with long messages is that when you send lots
of data to server, it's input buffer gets full and you get
killed from server because of "excess flood".
Irssi's current flood protection doesn't count the message
length, but even if it did, the CTCP flooder would still
be able to at least slow down your possibility to send
messages to server. */
