That's strange because when i run that patch on my system:

  % ./git; echo $?
  git: '' is not a git-command
 
  <list of common commands>
  1
  % ./git help; echo $?
  <list of common commands>
  0
  % ./git help -a; echo $?
  <list of all commands>
  0

That's what i was hoping this patch did. I'm not entirely sure how
its wrong as it seems to work for me.

Regarding "git: '' is not a git-command" the way i was seeing that
is that git is usually only called with commands, and '' isn't a
valid command, hence the reason to exit 1, the help is just a nice
user experience.
