it doesn't matter.  it's way down in the noise.

(but if you really want to know, the latter.  i use the former  
because it's clearer for me.  if you at the unparsed versions
of the commands:

	; echo {~ $#var 0} {~ $var}
	{~ <={%count $var} 0} {~ $var }
	; 


you'll see that the former has to do more work since it contains a  
superset of the operations in the latter.)
