- Y is either "city, state" or "city" or "state". So if there's a comma
with strings not containing numbers on either side we know it's city and
state. Otherwise: if there are two lines below, they are <state> and
<country>. If there's only one line below, it could be either the
state/province or the country.

This obviously won't work for all cases, but would probably be better
than
what it does now.  In particular, it will screw up in Canada, where you
could have either one of the following:

Montreal HF3 HT3
Quebec
