Ahhh... that makes sense. The files I'm working with were created on a DOS/Windows system and copied to my new Mac. Nano must've maintained the existing DOS LFs, and only offered Mac as the other format. (Converting it to a native, or Unix, format was not an option I saw within nano.) I'd probably be OK working with new files or files that Smultron has saved already with Unix LF. Thanks.
P.S. vi? I can if I have to, but I try not to have to!
