   It intentionally not done that way because, it would be too slow.
   The function in question is run every time a file is opened, and
   the VC systems are tried in the order they appear in
   `vc-handled-backends' until one matches...

I am not sure I buy this.  You already have to check if a file is
registered or not by executing git.  Doing `git rev-parse --git-dir'
or `git rev-parse --is-inside-git-dir' isn't that much more of a
headache.


And I'd rather have aslow, and correct behaviour than wrong and fast.
