   GIT_SSH
       If this environment variable is set then git fetch and git push
       will use this command instead of ssh when they need to connect to a
       remote system. The $GIT_SSH command will be given exactly two or
       four arguments: the username@host (or just host) from the URL and
       the shell command to execute on that remote system, optionally
       preceded by -p (literally) and the port from the URL when it
       specifies something other than the default SSH port.

       To pass options to the program that you want to list in GIT_SSH you
       will need to wrap the program and options into a shell script, then
       set GIT_SSH to refer to the shell script.

       Usually it is easier to configure any desired options through your
       personal .ssh/config file. Please consult your ssh documentation
       for further details.
