Subject: [PATCH v2 2/2] emacs: Make notmuch-show-next-thread return nil on failure
Date: Mon, 2 May 2022 17:18:50 +0200 [thread overview]
Message-ID: <20220502151849.6364-2-git@relevant-information.com> (raw)
In-Reply-To: <20220502151849.6364-1-git@relevant-information.com>
Having notmuch-show-next-thread return non-nil on success and nil on
failure makes it easier for users to interact with notmuch via elisp.
This commit changes notmuch-search-show-thread too since the return
value of notmuch-show-next-thread depends on notmuch-search-show-thread.

I've added docstrings and tests, but I'm not sure if the location I put
the tests in is appropriate.
