It looks like we're not handling the change from positive to negative
properly on a non-signed numeric field.

To handle it properly, the 6th bit in the last byte of the numeric field
should be turned off.   i.e.  "0" (0xf0) becomes "}" (0xd0), "1" (0xf1)
becomes "J" (0xd1), etc.

What we were (incorrectly) doing is concatenating a "}" to the end of
the field, no matter what the value of the field was.  Essentially, we
were always adding a zero to the end, and making it negative.

I've sent a patch to Sean Porterfield and Juan Rivas (who have both
mentioned this problem) and if they're happy with the results I'll
pass the patch along to Jason to be applied...


Thanks for all your help finding this stuff... :)
