[PATCH v4] test: emacs: new test "notmuch-search: change tags of all matching messages"

[Pieter Praet <pieter@praet.org>]

* test/emacs-search:

  - New subtest "notmuch-search: change tags of all matching messages":
    `notmuch-search-tag-all' (bound to "*") adds and removes tags
    to/from all messages which match the query used to populate the
    current search buffer.
