Yes. It is displayed correctly in notmuch-show mode, but try to reply
(press 'r') to the message and you will see. If you do not see it in
emacs, try running

  notmuch reply id:87r5o1etjb.fsf@steelpick.localdomain

and you will see the encoded headers. There is no problem with sending
such a mail. All recipients will see the headers decoded correctly. The
problem is, that I (the one who writes the reply) do not know what is
written in subject and what are the names of non-ascii named recipients.

If notmuch reply command decodes the headers, as implemented by the
patch, then Emacs (or some other part of mail sending chain?) will
encode the headers again before the message is actually sent.
