Why not just unset XDG_CONFIG_HOME?

Your match makes it look like XDG_CONFIG_HOME is required to use the
configuration directory, but it is not. To me, the main feature is the
ability to use $HOME/.config/git/ as a configuration directory (this is
not just a convention, this is a documented feature), and the management
of the variable $XDG_CONFIG_HOME is just a bonnus.

Before your patches, the correct management of $XDG_CONFIG_HOME to
override $HOME/.config/git/ was untested (which is unfortunate, indeed),
but after your patch serie, the fact that the default is
$HOME/.config/git/ is untested, which IMHO is even worse.

Unsetting XDG_CONFIG_HOME and adding one test like this would be better
IMHO.
