I don't know; it's possible.  I know that turning on truncate-lines
sometimes helps, but not always.  Some research is probably needed to
see if longlines-like solution is "good enough".

Also, if we decide that something like longlines is a reasonably good
solution, or the best we can come up with, I think we need a
stripped-down version of it, we don't need all the bells and whistles
of a full-fledged customizable minor mode.
