well the actual output is just:

:~$ git difff
git: 'difff' is not a git-command. See 'git --help'.


which is more or less the same as:

postgres=# \mysql
Invalid command \mysql. Try \? for help.

so I don't really see why we need to add some random second guessing of 
what the user actually wanted (and if he is indeed a mysql refugee he 
can always use "help" and go on from there).
