Normaiize/Standardize discrepancies with suffix in internal

[robe]

In writing book, noticed one discrepancy between normalize_address and pagc_address_parser. I suppose in some case the results may be right, though feels wrong.

SELECT * from normalize_address('1731 New Hampshire Avenue Northwest, Washington, DC 20010');

address|predirabbrev|streetname|streettypeabbrev|postdirabbrev|internal|location|stateabbrev|zip|parsed
1731||New Hampshire|Ave|NW||Washington|DC|20010|t

SELECT * from pagc_normalize_address('1731 New Hampshire Avenue Northwest, Washington, DC 20010');

address|predirabbrev|streetname|streettypeabbrev|postdirabbrev|internal|location|stateabbrev|zip|parsed
1731||NEW HAMPSHIRE|AVE||# NORTHWEST|WASHINGTON|DC|20010|t

To rule out my custom edits as being the culprit, I tested

SELECT * from standardize_address('lex', 'gaz', 'rules'
, '1731 New Hampshire Avenue Northwest, Washington, DC 20010');

address|predirabbrev|streetname|streettypeabbrev|postdirabbrev|internal|location|stateabbrev|zip|parsed
1731||NEW HAMPSHIRE|AVE||# NORTHWEST|WASHINGTON|DC|20010|t

I feel Northwest should be treated as a sufix rather than internal as it is with normalize_address, but not quite sure what to change here without messing up something else.

Fixed at r11743 for 2.2 and r11742 for 2.1
