Subject: [PATCH 1/6] Add test-script for git-merge porcelain
Date: Mon, 24 Sep 2007 00:51:40 +0200 [thread overview]
Message-ID: <1190587905-700-2-git-send-email-hjemli@gmail.com> (raw)
In-Reply-To: <1190587905-700-1-git-send-email-hjemli@gmail.com>
This test-script excercises the porcelainish aspects of git-merge, and
does it thoroughly enough to detect a small bug already noticed by Junio:
squashing an octopus generates a faulty .git/SQUASH_MSG.
