directional prefix ending up in directional postprefix (at least for highways)

[robe]

This is something I notices with brian's examples in #1077. I haven't added these to regress, since they don't behave right.

So for example:

SELECT pprint_addy(addy) As pp, addy.* FROM normalize_address('18208 N COUNTY ROAD 241, ALACHUA, FL 32615') AS addy;


                  pp                  | address | predirabbrev | streetname | streettypeabbrev | postdirabbrev | internal | location | stateabbrev |  zip  | parsed 
--------------------------------------+---------+--------------+------------+------------------+---------------+----------+----------+-------------+-------+--------
 18208 Co Rd 241 N, ALACHUA, FL 32615 |   18208 |              | 241        | Co Rd            | N             |          | ALACHUA  | FL          | 32615 | t

When the N should be in the predirabbrev column
