Subject: [PATCH 1/7] diff.c: emit_line_0 to take string instead of first sign
Date: Fri, 3 Aug 2018 18:53:11 -0700 [thread overview]
Message-ID: <20180804015317.182683-2-sbeller@google.com> (raw)
In-Reply-To: <20180804015317.182683-1-sbeller@google.com>
By providing a string as the first part of the emission we can extend
it later more easily.
While at it, document emit_line_0.
