Subject: [PATCH v7] diff: add config option relative
Date: Tue, 19 May 2020 21:39:02 +0200 [thread overview]
Message-ID: <20200519193902.GA202573@spk-laptop> (raw)
In-Reply-To: <xmqqv9krztwp.fsf@gitster.c.googlers.com>
The `diff.relative` boolean option set to `true` shows only changes in
the current directory/value specified by the `path` argument of the
`relative` option and shows pathnames relative to the aforementioned
directory.
Teach `--no-relative` to override earlier `--relative`
Add for git-format-patch(1) options documentation `--relative` and
`--no-relative`
Signed-off-by: Laurent Arnoud <laurent@spkdev.net>
