Yes, I'm very much in favor of this. I know I've been greeted by a wall
of usage text more than once and it does feel kind of intimidating.

I just tested this using a silly

  git clone a b c d e f

and the user experience is so much better after this patch. It's simply
"fatal: Too many arguments.", which is kind of neat, all things
considered. While one can always polish each error message individually,
hiding it behind a big usage dump feels wrong.
