No one really objected that strongly and I am specially limited the scope 
of what it does.  I plan to run it tomorrow unless I get some strong 
objections.  The only slightly controversial part might be the removal of the 
directional prefix.  But this is very easy to undue.

As I was trying to get at, my script specially does not address this.  I 
leave the name tags alone for the most part.  I saw a lot of this in the 
data I was working with and most of it will require manual cleanup. 
Perhaps a more specific example of what it does would help.

Something is clearly wrong with this tagging.  But since i don't know what 
to do with out I just clean it up a little.
http://www.openstreetmap.org/browse/way/10128991
IN:
   name: South 6130  West
   name_1: South 2nd West
   name_2: South 200 West
OUT:
   name: 6130 West
   name:prefix: S
   name:full: South 6130 West
   name_1: 200 West
   name_1:prefix: S
   name_1:full: South 200 West
Notice how name_2 is gone, as that is redundant.  To really fix it the 
way most likely it needs to be split in two.

Here is another mess:

http://www.openstreetmap.org/browse/way/10140212
IN:
   name: East Ninth South Circle
   name_1: 9th South Circle
   name_2: East 900 South
   name_3: East 9th South
   name_4: East 900  South
OUT:
   name: East Ninth South Circle
   name_1: 9th South Circle
   name_2: 900 South
   name_2:prefix: E
   name_2:full: East 900 South

So here, more could be done, but that can always be cleaned up better 
later.

And finally here is a nice clean case:

IN:
   name: East 900 South
   name_1: East 900 South
   name_2: East 9th South
OUT:
   name: 900 South
   name:prefix: E
   name:full: East 900 South
   loc_name: 9th South
