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.
