Subject: [PATCH 1/3] diff: move show_interdiff() from its own file to diff-lib
Date: Tue, 8 Sep 2020 03:16:08 -0400 [thread overview]
Message-ID: <20200908071610.16714-2-sunshine@sunshineco.com> (raw)
In-Reply-To: <20200908071610.16714-1-sunshine@sunshineco.com>
show_interdiff() is a relatively small function and not likely to grow
larger or more complicated. Rather than dedicating an entire source file
to it, relocate it to diff-lib.c which houses other "take two things and
compare them" functions meant to be re-used but not so low-level as to
reside in the core diff implementation.
