It does seem logical, but the code is obscure and it's not clear whether
this was intended or not---it probably fell through the cracks.  I don't
think the flag was completely thought through in other ways I've noticed
in the past, though I've forgotten what they are for the time being.
paramsubst() is full of my "one day someone should spend a year tidying
this up" comments.
