Also, to keep promise, mentioning 'patch' in commit message referring to the change introduced does IMO also look silly :D Tomi > _thread_set_subject_from_message (thread, message); > } > > if (date > thread->newest || ! thread->matched_messages) { > thread->newest = date; > - if (sort != NOTMUCH_SORT_OLDEST_FIRST) > + if (sort != NOTMUCH_SORT_OLDEST_FIRST || strlen(cur_subject) == 0) > _thread_set_subject_from_message (thread, message); > } > > -- > 2.1.2 > > _______________________________________________ > notmuch mailing list > notmuch@notmuchmail.org > http://notmuchmail.org/mailman/listinfo/notmuch
