Let's see: three votes for "cvs add -kb", two of whom said they didn't think that was the right way, and the third who hadn't used CVS in 6 years.
Two votes for "just check it in, ya coward", one of whom advised me to strip LF's before doing so.
And one who told me not to worry about Unix line-endings, because Notepad is the only Windows editor that can't deal with them. Well, guess what folks: Notepad is the only Windows editor I've ever used. D'you wonder why I run screaming in terror? ;-)
So I stripped the LF's and just checked the damn things in. Guess I'll find out if I screwed up soon enough. Thanks for your help!
(PS. I recently learned that there's an Emacs command -- M-C-% -- that uses all three standard shift keys on a PC keyboard -- awesome! My life is now complete...)
