Well, in that case, then the opposite but an equivalent problem
exists in the design, no?  It promises to make roots stand out by
painting them as 'o', but it sometimes fails to do so.  In other

That's another way to do so, but shifting columns to show where the

provides more information by default, etc., and a big plus is that
it would be an approach to do so without having to go beyond ASCII.
