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.

Whatever, you are happy with nvi, I'm happy with vim, so be it.  Though
I'm teaching my kid vim because I strongly suspect vim is much more
widely used.  This is starting to feel like a BSD vs Linux argument and
we know how that turned out.
