[PATCH] Allow multiple rcirc connections to the same host

[Andreas Rottmann]

Hi!

The attached small patch allows the `rcirc' command to connect to the
same host multiple times when the port numbers differ.  This is
especially useful when using e.g. SSH forwarding to the IRC server, for
instance when connecting to an irssi proxy.

Also, it displays the port number on "Already connected", "Quit
connecting", and "Connecting to" messages.

From: Andreas Rottmann <address@hidden>
Subject: Allow multiple rcirc connections to the same host

* lisp/net/rcirc.el (rcirc): When collecting the already-connected
  servers list, consider both hostname and port, instead of hostname
  only.  Also take the port into account on the messages displayed.
  (rcirc-connect): Include port number in "Connecting to" message.
