What is the deal with VISUAL and EDITOR? I always set EDITOR; I've never
set VISUAL. I've never understood what the difference is.
EDITOR specifies a line editor (ed, ex, etc). VISUAL specifies a full
screen editor (vi, emacs etc). Virtually no one uses line editors any
more, but there are still a few holdouts and the cost of supporting
VISUAL -> EDITOR -> ed/vi/whatever is minimal.
