+\r
+The `notmuch-show-mark-read-tags' lists tags that are to be applied when\r
+message is read. By default, the only value is "-unread" which will remove\r
+the unread tag. Among other uses, this variable can be used to stop\r
+notmuch-show from modifying tags when message is shown (by setting the\r
+variable to an empty list).\r

+ I've sent this patch a while back but I think it got lost somehow so\r
+ resending.\r
