commit fe89760bc71a08cb3d708774e4ad42f763384d98
Author: Andrew G Cohen <address@hidden>
Commit: Andrew G Cohen <address@hidden>
Speed up marking read messages in nnselect
* lisp/gnus/nnselect.el (nnselect-request-update-info): Update the
list of read messages by excluding the unread ones. Since the
list of unread messages is usually shorter than the read list, this
speeds things up significantly.
