+Eighth in the increasingly inaccurately named six patch series...\r
+\r
+Quoth Dmitry Kurochkin on Jan 28 at 9:59 am:\r
+> Before the change, `notmuch-show-operate-all' used thread id for\r
+> "notmuch tag" search. This could result in tagging unexpected\r
+> messages that were added to the thread after the notmuch-show buffer\r
+> was created. The patch changes `notmuch-show-operate-all' to use ids\r
+> of shown messages to fix this.\r
+\r
+Are you planning to roll this into your earlier patch?\r
