 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!
