this is what Lynx apparently does, but i would argue it's wrong in practice,
because it would be hopelessly bad HTML for anyone to start a  <pre>  block
without finishing it, so Lynx should assume there will be a  </pre>  later,
if only at the very end of the HTML.
we then have a choice to treat  <center>  as centring <pre>'d `text',
or treat  <center>  as overriding  <pre>  temporarily,
so that `text' is centred but otherwise treated as  non-<pre> :
if the latter, Lynx should insert  <pre>  following  </center>
when it finds it, ie immediately before the final `text' above.

Lynx should do its best to make sense of common inaccurate HTML out there,
with a  -stricthtml  switch for those who are straight & narrow (smile).
