Works for me.  B-)

I did not mean the functionality of scrolling text, I meant using escape
sequences for scrolling text.  It already scrolls text, it just does a
screen redraw instead of trying to figure out which bit of the screen
it can scroll with escape sequences first before drawing the rest.

This is one of the reasons I was checking if we ever have to deal with
slow connections.  Fast ones can handle complete redraws for paging
and scrolling, and that keeps the code simple.  Optimized redraws can
come later if we feel it's needed.

I would not use vi or emacs, so it's gonna do what ever I like as an
editor as well as those two.  Once it can deal with the horrid vi
command and insert modes, which are no longer needed, just ancient
historic artefacts, then a simple emacs editor is just a matter of
different key bindings.

It's gotta scratch my itches as well, or it's not worth my time.  And
people will scream if I leave out emacs.  shrugs
