        Why not instead heed the bad HTML statusline message which
precedes the stack overrun, and suggest that something be done
about all those invalidly unclosed Anchors?  Increasing the stack
for nested container elements beyond 800 will just increase the
size of the Lynx image, but won't help Lynx with such severly bad
HTML.  The bad HTML statusline message is not "didactic" as some
presume.  It is issued *only* when the HTML is so bad that Lynx
has little if any prospect of coping with it (though sometime it
does 8-).
