Well, up till now our policy has been that in the context of
printf and sprintf, we do @-string substitution only in the
format portion of the command line, and not in the arguments
portion. I think there was a reason for that, but I can't
reconstruct it right now. Perhaps we're being too
restrictive; I need to think about it a bit more.
Having thought about this, it seems to me it would be more
consistent to do @-substitution in the arguments to printf and
sprintf. This is now in CVS and snapshots. Please report any
undesirable side effects!
