XEmacs 21.0: Scrolling with Continuation Lines
When I set truncate-lines to nil and scroll through a buffer I sometimes
find that the text disappears off the left hand side of the screen. This
is a bug, I think, rather than a feature, because with the continuation
lines in effect there is no need to do this; the text would be visible, and
editable, without this automatic scrolling.
