Subject: [PATCH v8 01/10] pull: refactor fast-forward check
Date: Tue, 24 Nov 2020 21:29:29 -0600	[thread overview]
Message-ID: <20201125032938.786393-2-felipe.contreras@gmail.com> (raw)
In-Reply-To: <20201125032938.786393-1-felipe.contreras@gmail.com>

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