Summary: The documentation is explicit that Git does not pass this flag: The $GIT_SSH command will be given exactly two arguments: the username@host (or just host) from the URL and the shell command to execute on that remote system. This isn't true; it does. Accommodate it. I'll see if I can fix this in the upstream, too. Test Plan: Ran various `ssh-connect` commands with -p, etc. Reviewers: btrahan Reviewed By: btrahan CC: aran Differential Revision: https://secure.phabricator.com/D7680
