Subject: [PATCH 1/4] git-merge: Honor pre-merge hook
Date: Fri, 22 Sep 2017 14:04:12 +0200 [thread overview]
Message-ID: <053ce92e978aff511667669682c9a71830008605.1506081120.git.git@grubix.eu> (raw)
In-Reply-To: <cover.1506081120.git.git@grubix.eu>
From: Michael J Gruber <git@drmicha.warpmail.net>
git-merge does not honor the pre-commit hook when doing automatic merge
commits, and for compatibility reasons this is going to stay.
Introduce a pre-merge hook which is called for an automatic merge commit
just like pre-commit is called for a non-automatic merge commit (or any
other commit).
