I suspect this can be reduced even further. There used to be a nifty trick for
doing this on 8080 and Z80 micros, which used the half carry flag. The PIC also
has this flag available, so if anyone has an 8080 Cookbook or Z80 Cookbook handy
they may like to look it up. From memory it totally does away with the skip
instruction because you do not need to distinguish if it <=9 or >=A.

actually on reflection looking over what I have written, I believe the technique
was involved in converting a HEX nibble to ASCII, so may not be applicable here.
