Hmm, when I tried nvi I don't think it had :E or I missed it. I read
release notes so it's strange I didn't catch it. Or maybe it was added
later because Keith was pretty focussed on 100% vi compat and I never
saw :E in vi either.
vi didn't have this feature (or multiple undo/redo). Looking at
nvi logs, split windows were added on April 5, 1993 by Bostic.
