-U is a handy option for developers wanting to test Unicode
conformance of their code, but the help message promised more than it
could deliver. Please leave this alone.

Long digits are only 15 bits, so if you change it to return an
unsigned short that shouldn't matter. Dunno if there's magic for
negative numbers though (in memory, the length is negative, but the
digits are not).
