ssh-diff - diff a file over SSH

       diff a file over SSH

       There is an extra roundtrip to the remote system
       to check for the existence of the file to be diffed.
       So if you are not using SSH Keys
       you may get prompted twice for a password.

       Use "CHECK_REMOTE_FILE_EXISTS=NO ssh-diff" to disable that behavior

       All options your local diff command supports ( except '-r' ).
       See 'man diff' and 'diff --help' for more information.
