	* gnus-agent.el (gnus-agent-possibly-synchronize-flags): Ignore
	servers that are offline.  Avoids having gnus-agent-toggle-plugged
	first ask if you want to open a server and then, even when you
	responded with no, asking if you want to synchronize the server's
	flags.
	(gnus-agent-synchronize-flags-server): Rewrote read loop to handle
	multi-line expressions.
	(gnus-agent-synchronize-group-flags): New internal function.
	Updates marks in memory (in the info structure) AND in the
	backend.

	* gnus-util.el (gnus-remassoc): Fixed typo in documentation.

	* nnagent.el (nnagent-request-set-mark): Use
	gnus-agent-synchronize-group-flags, not backend's request-set-mark
	method, to ensure that synchronization updates marks in the
	backend and in the info (in memory) structure.
