Subject: [PATCH v10 10/10] cherry-pick/revert: add scissors line on merge conflict
Date: Wed, 17 Apr 2019 11:23:30 +0100
Message-ID: <20190417102330.24434-11-phillip.wood123@gmail.com> (raw)
In-Reply-To: <20190417102330.24434-1-phillip.wood123@gmail.com>

From: Denton Liu <liu.denton@gmail.com>

Fix a bug where the scissors line is placed after the Conflicts:
section, in the case where a merge conflict occurs and
commit.cleanup = scissors.
