Subject: [PATCH v4 4/5] format-patch: teach --no-base
Date: Wed, 4 Dec 2019 13:25:06 -0800
Message-ID: <eb35de8f4917a406d886a6da4180d2d90e95e633.1575494618.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1575494617.git.liu.denton@gmail.com>

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