Subject: [PATCH 4/5] format-patch: teach --no-base
Date: Tue, 26 Nov 2019 18:09:19 -0800	[thread overview]
Message-ID: <e072c36e6a41ef70d2a15c052c672f94b54ce930.1574820308.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1574820308.git.liu.denton@gmail.com>

If `format.useAutoBase = true`, there was no way to override this from
the command-line. Teach format-patch the `--no-base` option which
overrides `format.useAutoBase`.
