* gnus-int.el (gnus-open-server): Fixed the server status such
that an agentized server, when opened offline, has a status of
offline. Also fixes bug whereby the agent's backend was called
twice to open each server.
* gnus-start.el (gnus-get-unread-articles-in-group): Autoload
gnus-agent-possibly-alter-active rather than inline to resolve
compiler warnings.
* gnus.el (gnus-server-to-method): Added fallback of iterating
over gnus-newsrc-alist to resolve names of foreign servers.
Should fix recent agent bug.
