Text editor recs?

[brownbetty]

I want a command line text editor that can do a soft-word wrap. By "soft," I mean that long lines won't scroll past the right edge of my screen, but when I save my file, I won't discover it's had a mess of line breaks inserted into my text every seventy-odd chars.

I'd be mostly writing in natural English, so emacs or vi are rather more complicated than I'm looking for, but if you tell me one of them is my only solution, I will cry and then suck it up and learn to use whichever.
