I thought of a quite different approach - basically, to make a minimalized
version of the display_page() function which only redraws one (or maybe
two) line(s), and skips all the rest.  That could then be used instead of
highlight(..,OFF), I thinks it's not too much overhead to rewrite a full
line instead of just the anchor text.   If it works, it should ensure that
the line is redrawn the same way as the first time, since it would use the
same data (with included underline/bold switching information).
Additional advantage is that highlighted WHEREIS search text could also be
restored.

Well at this point it is just an idea.  (Maybe someone else wants to do
it?)  I don't know how this idea would interact with (whatever version of)
Rob's code.
