HTML like "Line One <P></P> Line Two" causes 2 line breaks on
navigator but only 1 in raptor.  This was causing the news headslines in the
right most column of the ESPN page to squich together vertically.
This likely has something to do with special P-element-specific code that kipp
wrote based on comments in the HTML spec.  I tend to think those comments
weren't intended quite as written, but just to require CSS-style
margin-collapsing.

According to a strict reading of the specs, <p></p> should be ignored, which
means that in fact we should not even be causing a line break there.
Summary: <P></P> causes two line breaks on navigator, but only 1 on raptor → <P></P> should not be ignored in NavQuirks mode {ll} {compat}
I don't think the HTML spec needs to be read that strictly... and anyway, I
*think* it says "should", not "must".
That's what I said! "should"! :-)

It says: "We discourage authors from using empty P elements. User agents should
ignore empty P elements." (end of section 9.3.1)

Just out of interest, are there any other sites that use this kind of markup?
(...and could someone list them? I may wish to evangelise.)

Also, what exactly is the behaviour we want? We can't just use CSS rules, 
otherwise CSS starts bordering empty P paragraphs, and such like. And if an
author uses padding instead of margins on <P> elements, then all kinds of 
weird things start happening, none of which look like us ignoring paragraphs.

Incidentally, the fix for this should be "simply" to bypass Kipp's "ignore 
empty P elements" code if the empty <P> element is flanked on both sides by 
inline elements or anonymous inline boxes (i.e., raw text). In quirks mode 
only, of course.

I'm not even sure this should be quirks mode only.  See the thread on www-html
beginning with http://lists.w3.org/Archives/Public/www-html/2000Apr/0024.html .
Since the rules changed, this is now a dup of 35768.

Ian, I think you missed the right bug on the DUPL. bug #35768 is about applying
style for :lang elements, no?

Err, not bug 35768, sorry. I meant bug 35772.
