Complete success would mean the full page as resized looks like it would
if Lynx started at that size. I have tried combos of ^R, ^W, ^L without
being able to get a usable screen after resize. The main symptom is
that moving from link to link will land the cursor in the wrong place,
redrawing text in the wrong position during the move.

I see the same effects on NetBSD/XFree86 going back to one of the
lynx2-6 binaries I have. I also see similar symptoms under DIGITAL UNIX
where screen resizes confuse the underlying screen layout logic.
