The 'GIT_DIR' environment variable is set up for the remote helper
and can be used to determine where to store additional data or from
which directory to invoke auxiliary git commands.
When git encounters a URL of the form '<transport>://<address>', where
'<transport>' is a protocol that it cannot handle natively, it
