HylaFAX

The list of dialrules is quite small. Please add those from
http://lahtermaher.org/pub/packages/hylafax/contrib/dialrules/, especially
the rather antique dialrules.ext for handling extensions and locations that
require a leading "9," to dial out. In fact, if you look for dialrules.ext
and HylaFAX on Google, you'll mostly find me publishing it or pointing it
out to people.

It would also be useful to reset the default references to "dialrules" to
point to "dialrules.usa", and name the dialrules file appropriately. The
unspecified defaults are rather confusing.
