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`
