Subject: [RFC PATCH 1/5] format-patch: allow additional generated content in make_cover_letter()
Date: Wed, 30 May 2018 04:03:21 -0400 [thread overview]
Message-ID: <20180530080325.37520-2-sunshine@sunshineco.com> (raw)
In-Reply-To: <20180530080325.37520-1-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.
