Subject: [PATCH 03/12] xmerge.c: minimum readability fixups
Date: Fri, 29 Aug 2008 17:42:34 -0700 [thread overview]
Message-ID: <1220056963-2352-4-git-send-email-gitster@pobox.com> (raw)
In-Reply-To: <1220056963-2352-3-git-send-email-gitster@pobox.com>
This replaces hardcoded magic constants with symbolic ones for
readability, and swaps one if/else blocks to better match the
order in which 0/1/2 variables are handled to nearby codepath.
