Yeah.  It seems to me that the thing would/should know that it has 
nothing to do.  It's sorta like writing a program to find the first 
prime number divisible by two, the program will run for a long time 
without producing much.  I'm wondering if the devs just overlooked that, 
or if perhaps the idea of completion on an empty string might actually 
have some sort of meaning.  Completion seems to be such a complex thing 
that maybe it does -- the sound of one hand clapping.
