> Undo-ing is clearly a non-trivial feature. I wrote my own editor (zedit or z) in the late '80s. At that time none of the editors I was using had undo... so I didn't add it. It wasn't until I switched to emacs a decade later that I had undo. I added undo to z. It works 100% of the time in testing... but only about 80% of the time if doing real heavy editing. Luckily I only use z for light editing now, so the undo is good enough. Basically, I agree that undo is hard. Cheers, Sean P.S. I lost the link to the source code for edit. Could you resend it?
