The documentation specifies the termination conditions for negative
and positive increments, but it does not specify the termination
conditions for 0 increments (which are neither positive nor negative).

It appears that the Laswerwriter and the DPS on the DecStation treat
0 as a negative increment (terminates when the control variable is
less than the limit), whereas NeWS treats 0 as a positive increment
(terminates when the control variable is greater than the limit).

The redbook should be revised to be explicit about the zero case.
