I've thought about it when you brought up the Andrew's naked git
repository detection issue, but one thing I was undecided was
that if we would want to forbid either of these "directories"
being a symlink to another directory.  I think it would be OK;
admittedly "test -d" says OK for a symlink to a directory.

I accept the patch, but will not apply and push it out right
now; I am not in a shape to be operating heavy equipment ;-).
Please wait until tomorrow morning.
