Subject: Fix inloop if the server dies before the async -finish is called
X-Git-Url: http://cgit.sxemacs.org/?p=gnus;a=commitdiff_plain;h=73c8c3d05a901debb46e70f32f125ab4fa3ba540

Fix inloop if the server dies before the async -finish is called

* nnimap.el (nnimap-open-server): Allow switching the nnoo server
without reconnecting.
(nnimap-possibly-change-group): Ditto.
(nnimap-finish-retrieve-group-infos): Don't reconnect if the server
connection has died before being called.
