Hi David, dear notmuch developers,

I finally isolated two such threads, anonymized them and indexed
them.  tar'ed and compressed the maildir is small enough to attach,
therefore I attached it.


With the first thread (Ticket 33712) notmuch shows the "-->"
marked email last in thread, instead (as according to date sent)
before position marked "+++":

      [support.xxxxxxxxxxx-xxxxxxxxx-xxxxxxxxx.de #33712] xxxxxxx-xxxxxxxxx-server xxxxxxxxxxxx

With the second thread the email marked "-->" should be at the
end, IMHO.  I don'nt know how this Resolved-Message is produced,
perhaps it is not a reply to the last message in thread:

      
      [support.xxxxxxxxxxx-xxxxxxxxx-xxxxxxxxx.de #33575] AutoReply: FYI: xxxx  xxxxxxx  xxxxxxxxxxxx xxx
       via RT <rt-xxx@xxxxxxx-xxxxxxxxxxxxxxxxx-xxxxxxxxx-xxxxxxxxx.de> (Tue, 26 Jun 2018 14:44:24 +0200) (inbox)
