Subject: [PATCH v4 2/2] repo: add --all to git-repo-info
Message-ID: <20251117151844.14802-3-lucasseikioshiro@gmail.com>
In-Reply-To: <20251117151844.14802-1-lucasseikioshiro@gmail.com>

Add a new flag `--all` to git-repo-info for requesting values for all
the available keys. By using this flag, the user can retrieve all the
values instead of searching what are the desired keys for what they
wants.
