[PATCH 5/7] Try to do things in the right order

[Xavier Maillard <zedek@gnu.org>]

* 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
