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.
