[PATCH v1 0/4] maintenance: use XDG config if it exists

maintenance: use XDG config if it exists

I use the conventional XDG config path for the global configuration. This path is always used except for `git maintenance register`.

§ Other discussions

While working on this series I found that Phillip Wood[1] had pointed out that `xdg_config` is never used. However that was on a series where this was the existing behavior (not new), so this wasn't acted upon.
