[PATCH 1/1] emacs: Make notmuch-show-next-thread return nil on failure

[Leo <git@relevant-information.com>]

From: Leo Okawa Ericson <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.
