That's the correct behavior.
  
OK, thanks for the explanation.  It makes sense, although I think it's 
just a little gross. ;-)

To avoid pitfalls like this, always quote variable expansions.  The [[
command is also less tricky.
  
Yes, I know that, but the person who wrote the code in which I noticed 
this issue apparently does not :-).

Thanks again,
