[FUN PATCH] Remove "git clone" parameters if they are the first in a git clone call

This removes accidental duplicate "git clone" parameters, for example
when typing:

  git clone git clone git://repo.or.cz/git.git

---

OK, so it happens often to me that I copy a line that already starts with "git
clone", and then type it myself again, paste, and hit enter. I thought it
might happen to others too, hence this patch.
