No, you didn't.
As i told already the example //A6144(M)//  given in the filter code 
busts the shield on my 60csx , so that it's not looking nice.
(maybe thats depending on the device you have).
"A6144(M)" is the max. length i saw in an original garmin map of europe.

Depending on the letter you use ( they needs different space for 
displaying) i would say 6-8 sign are really enough.
More you not want have as it really clutters up the display.

The idea of reducing it to 5 signs isn't good as there exist e.g in 
Italy shields like "S45BIS", "A26DIR" or "ST2018a" in Germany.
or "D763 B1" in France.
And reducing it to 3 sign in the case if no numeric is present doesn't 
bring any benefit and e.g. may constrain those who use it for marking 
hiking trails and other stuff.

The  "BUS US-127" is simply to long for displaying it in a highway 
shield on GPS.
Isn't there a way dealing with this via stylefile?. e.g looking up the 
content of REF and checking if there is a "BUS " at the beginning and 
then cutting of this "BUS " so that only "US-127" remains  which then is 
displayable ?
Just an idea of a poor man having less experience with style files.
