bug#4589: 23.1; ERC reconnection -vs- /disconnect

[Tom Tromey <tromey@redhat.com>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


One irc server I use went down and was unavailable.
ERC kept trying to reconnect to it -- which is nice, ordinarily I want
this.
However, in this case, I wanted to prevent ERC from trying to reconnect.

So, I went to the server buffer and typed /disconnect.
This did not work, instead ERC gave me an error message
(which I no longer have but the gist was that there was no connection).

I think /disconnect should work to prevent reconnection in this
situation.
Instead, the only solution I found was to kill the server buffer.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.
