* emacs/notmuch-show.el

  (notmuch-show-get-messages-ids):
    New optional argument ONLY-OPEN.  If non-nil, only return
    Message-Id's for messages which are currently visible.

  (notmuch-show-tag-all):
    New optional argument IGNORE-VISIBILITY, of which the inverse is
    passed as ONLY-OPEN argument to `notmuch-show-get-messages-ids':
    If called with a prefix arg, affect *all* messages in the current
    buffer.  Otherwise, only change tags of visible messages.

  (notmuch-show-archive-thread):
    Update wrt changes to `notmuch-show-tag-all'.

* test/emacs

  - Subtest "notmuch-show: change tags of open messages in current buffer"
    is no longer broken.
