Subject: [PATCH 01/14] format-patch: allow additional generated content in make_cover_letter()
Date: Sun, 22 Jul 2018 05:57:04 -0400 [thread overview]
Message-ID: <20180722095717.17912-2-sunshine@sunshineco.com> (raw)
In-Reply-To: <20180722095717.17912-1-sunshine@sunshineco.com>
make_cover_letter() returns early when it lacks sufficient state to emit
a diffstat, which makes it difficult to extend the function to reliably
emit additional generated content. Work around this shortcoming by
factoring diffstat-printing logic out to its own function and calling it
as needed without otherwise inhibiting normal control flow.
