Nice; it works well!

However, I do have a message for which `^' finds the parent article via
nnir but where `C-u A T' fails, saying the search produced no results.
On the other hand, when I execute the nnir IMAP search I prescribed in
the other thread

  or (header message-id <AANLkTimeXrbYJDTmXhBWsOMg-jEmfJ9T4TdcVLuuHCfy@mail.gmail.com>) (header references <AANLkTimeXrbYJDTmXhBWsOMg-jEmfJ9T4TdcVLuuHCfy@mail.gmail.com>)

it works perfectly.  So something is not quite sufficient in the query.
