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?
