This breaks git-apply when used to just do a "diffstat", or when used on a 
non-git repository.

For "git-apply --stat", we definitely don't want to force it inside a git 
directory. In fact, even _trying_ to find a git directory would be wrong.

The only case where we care about a git directory is the "--index" case. 
In all other cases we should happily apply it (or stat it).
