Isn't it sufficient to add a new configuration variable in the
clone.* namespace?  Unless there is a reason why it does not work, I
won't accept a patch that adds a random environment support like
this.  We do not want to end up having to add other random
environment variables like GIT_CLONE_DEFAULTREMOTENAME,
CLONE_REJECTSHALLOW, CLONE_FILTERSUBMODULES for consistency.
