Yeah, I was forgetting that "for" was interpreting the spaces as
delimiters, just like it's supposed to be doing.  I was thinking
it was the shell that was interpreting the spaces and that
escaping them would fake it out, but it was "for" all along.  I
should have just used a "while read var" statement.  Doh.  :-)
