* emacs/vc-git.el: Added an ugly hack to properly reload vc-git. Only
  add GIT to vc-backends list after loading vc. Do not walk .git
  directory (add it to the exclusion-list).

  Changed installation instructions as discussed on Git mailing list

That's ugly. Simply recommending that users set vc-handled-backends in
their .emacs is easier and cleaner, I still don't see why you want to
change it.

I'd rather want to just require or load vc-git (and that should
not be the way to go too since it should be automatically handled
by vc.el when vc-git will become part of GNU Emacs ).

By the way, do you plan to ask for inclusion into emacs ?

That's just a matter of taste, nothing more.
