Oh. I did a subset of the p [:line, line] and it looks like i had some 
\n and some  \r\n occurring. I was just pulling the \r\n on my sub call 
(wrote it as \n to simplify)because when I was looking at the original 
with end of line showing they all showed as CRLF. Odd.
Much improved output, and another tool in my meager toolkit. Thanks so 
much, Noah and all other repliers! I'll look at replacing the each with 
map/collect now that I know about it. I do have the Pragmatic 
programming book...
Cheers, Gani
