empty is zero

[Mark Schonewille]

Scott,

empty = 0 --> empty doesn't get parsed
empty * 1 = 0 --> empty gets parsed

tParam gets *parsed* because it is passed on to a handler. Parsed, hence

tParam = 0 --> true.

Just consider this a fact. It may not be entirely logical, but it  
isn't too difficult to remember and it is easy to work around.
