I *knew* that there were only two false strings, but yesterday, on a 
whim, I tried #3 and (to my surprise) found it to be *false*. 
Unfortunately, I can't recreate that experiment today, so I guess I'm 
back to my original beliefs, based on the documentation you provided.

Anyone know how I may have gotten "\000" to be hint that it's false?
