Thinking about this point again, and it goes for 'loopif' as well, do
we wish to use zero or non-zero? If we ever have something akin to
$(command), command's return code should be zero on success. I made an
error in the last e-mail saying that this could stay as non-zero if we
ever had $(command)-style support.<br>
