Yeah. If we were to go with Greg's suggestion of inventing a separate
is_relative_to_cwd test function, I'd expect that to insist on no ".."

That seems like a fairly clean approach in the abstract, but I agree
that somebody would have to look closely at each existing usage to be
sure it works out well.
