What is the sign of zero? ;) IEEE zeros do have a sign, so we should
print them.

The Hyperspec isn't clear about this either, but Clisp prints
"+0"... hmmm.  The docs say that the sign is always printed, and the
canonical sign of zero is +, so we should print a "+".

Please make that change, then!
