Subject: [PATCH v4 03/19] pull: refactor fast-forward check
Date: Mon, 7 Dec 2020 18:26:32 -0600 [thread overview]
Message-ID: <20201208002648.1370414-4-felipe.contreras@gmail.com> (raw)
In-Reply-To: <20201208002648.1370414-1-felipe.contreras@gmail.com>
This way we will be able to do the check unconditionally (merge or
rebase).
