The web browser "Lynx" does something very similar.  One addendum to the
above logic is that if the DNS look-up fails, it tries to use the string
as a local file path.

Typo the FQDN in a URL to something that returns NXDOMAIN, and you get an
error message to the effect that lynx 'couldn't access start *FILE* "foo'"
(emphasis added.)
