* gnus-start.el (gnus-activate-group): Take an optional parameter to
say that you don't want to call gnus-request-group with don-check, but
do check the reponse. This is for virtual groups only.
+ (gnus-get-unread-articles): Count the archive groups as secondary, so
+ that they're activated the same way as before.
* imap.el (imap-message-map): Removed optional buffer parameter, since
no callers use it.
