Why shouldn't it be? It's in a context where url-handler-mode is
deactivated, so Emacs has no reason to presume that it's a URL.

Which might be the right thing to do.

If d:/gnu/bzr/emacs/trunk/http:/foo.com/wherever/ exists, then I'd argue
it was the right thing to do.

The name *is* ambiguous. The only reason such ambiguity is frequent and
non-problematic is because conflicts rarely arise. So I don't consider
this to be luck. It's basically by design (design of the URL name space).

The correlation is weak. I don't think this heuristic is worth much if
anything in this context.

It's better because all the checks are *directly* related to the problem
at hand: detecting non-absolute file names which include
a directory component.
If you only care about simpler, then we can just remove the
file-name-handler check and only rely on the faccess check.
That should work just as well.
