So, I have been playing with subst and some virtual drives, and this
allows to run builds if for example pointing to the top of a git repo,
which is fancy.

Requiring at least three repository levels is something that we are
going to need anyway as a build requires a full access to the tree,
but I really see no reason to help users with such configurations as
that's basically free for us to do so.  I can see the difference of
output between cl /? and /help for virtual drives, and that's really
surprising, but I see no reason to not apply this patch as this breaks
nothing and /help is an official option.

If there are no objections, I am planning to apply this patch to
HEAD.
