bug#10162: 24.0.91; rcirc autojoin broken (freenode/oftc) when rcirc-authenticate-before-join is set

[Trent W. Buck]

When doing emacs -f irc or M-x irc, Emacs would connect to all three
servers, but not autojoin channels in Freenode with this setting:

    (setq rcirc-server-alist
          `(("irc.freenode.net" :channels ("##workingset"
                                           "#collectd"
                                           "#emacs"
                                           "#lxcontainers"
                                           "#netfilter"
                                           "#paredit"
                                           "#screen"
                                           "#ubuntu-hardened"
                                           "#ubuntu-server"))
            ("irc.oftc.net" :channels ("#debian-au"
                                       "#debian-derivatives"
                                       "#debian-eeepc"
                                       "#debian-haskell"
                                       "#debian-mentors"
                                       "#debian-next"))
            ("irc.cyber.com.au" :channels ("#cyber"))))

I tried moving freenode to be the last of the three; the result was that
only #cyber was joined.

As a random guess, I tried (setq rcirc-authenticate-before-join nil) --
this fixed the problem.

I speculate there is an issue with this new feature when >1 server is in
the server alist.  I could reproduce this behaviour reliably with a
dozen or so attempts under emacs-snapshot; I never had this behaviour
under 23 (which predates authenticate-before-join).

I also had this problem several months ago with the emacs-snapshot that
was current then; I didn't bother to investigate at the time -- it was
easier to just switch back to 23.

irc.cyber.com.au is an internal (private) office IRC server; running
ircd-irc2 2.11.2p1+dfsg-2 on Ubuntu 10.04 (Lucid).

A complete (but slightly older) copy of my emacs configuration can be
found at http://cyber.com.au/~twb/.emacs and
http://cyber.com.au/~twb/.rcirc.el.
