Subject: [PATCH v2 03/14] pull: refactor fast-forward check
Date: Fri,  4 Dec 2020 00:16:12 -0600	[thread overview]
Message-ID: <20201204061623.1170745-4-felipe.contreras@gmail.com> (raw)
In-Reply-To: <20201204061623.1170745-1-felipe.contreras@gmail.com>

This way we will be able to do the check unconditionally (merge or
rebase).
