Oh, This should have been C/E instead of C/R. Current/End. 'e' and 'r'
keys are just too close to each other :-)

Yes, I think that's the best. Then we have documented to apps higher in

a definitive answer; in all other cases, we have fudged data so that
higher layers don't have to worry about 0/0.
