        <CENTER>, which has been formalized in the W3C's so-called
HTML standards as "shorthand" for <DIV ALIGN="center">, is not, in
fact, valid within a PRE block.  The devel code's "SortaSGML" parser
thus closes the current PRE block (inserts an artificial </PRE>) on
encountering the CENTER start tag, and cannot recover to the PRE
block on detection of the CENTER end tag.  That behavior is technically
"correct", but incompatible with that of virually all other browsers.

        I'm puzzled at your claim that lynx2-7-1 doesn't handle that
markup as the provider intended, because it's "TabSoup" parser should,
and does, when I try it.  The devel code's "TabSoup" parser did not
keep up with enhancements that were made in it for the fotemods, and
is still essentially that of the v2.7.1 release, but it does render
that markup as the provider intended when I toggle it on via the
-89 devel code's ^V command.
