Subject: [PATCH v2 3/9] Add a function to update HEAD after creating a commit
Date: Fri, 10 Nov 2017 11:09:43 +0000 [thread overview]
Message-ID: <20171110110949.328-4-phillip.wood@talktalk.net> (raw)
In-Reply-To: <20171110110949.328-1-phillip.wood@talktalk.net>
From: Phillip Wood <phillip.wood@dunelm.org.uk>
Add update_head() based on the code that updates HEAD after committing
in builtin/commit.c that can be called by 'git commit' and other
commands.
Signed-off-by: Phillip Wood <phillip.wood@dunelm.org.uk>
---
Notes:
changes since v1:
- rename update_head() to update_head_with_reflog()
