Subject: [PATCH 04/14] interdiff: teach show_interdiff() to indent interdiff
Date: Sun, 22 Jul 2018 05:57:07 -0400 [thread overview]
Message-ID: <20180722095717.17912-5-sunshine@sunshineco.com> (raw)
In-Reply-To: <20180722095717.17912-1-sunshine@sunshineco.com>
A future change will allow "git format-patch --interdiff=<prev> -1" to
insert an interdiff into the commentary section of the lone patch of a
1-patch series. However, to prevent the inserted interdiff from
confusing git-am, as well as human readers, it needs to be indented.
Therefore, teach show_interdiff() how to indent.
