Subject: [PATCHv2 4/4] t7503: add tests for pre-commit hook (merge)
Message-ID: <084ade976d944576da58c8334ffec5e47b209421.1346939542.git.git@drmicha.warpmail.net>
In-Reply-To: <50487F8A.4050803@alum.mit.edu>

Add tests which make sure that the pre-commit hook is called by 'git
merge' when merge.usePreCommitHook is set, allows/disallows merge
commits depending on its return value and is suppressed by
"--no-verify".
