Markdown tries to avoid wrapping paragraphs around things they're not
allowed to contain, but it misses the mark often enough to be
dangerous:

    Like when you <div>don't skip lines</div> around HTML blocks.

or

    <p>...when you omit close tags.

or

    <div>
    <div>
    ...when the parser gets confused (try this one in Showdown or
Markdown 1.0.2b2).
    </div>
    </div>

Those cases could be handled with a couple of fixes to the
text::balanced HTML parser (and a brand new parser for Showdown).

I'm guessing the other cases of extra paragraphs are mostly things like this:

    <div>
      <div>
        This is just one line, so I don't want it wrapped.
      <div>
      This is just one line following a block element, so I don't want
it wrapped.
     </div>

...which can be handled by saying "don't make solitary paragraphs" and
"count block elements as paragraph breaks."

I'm sure there are other examples that generate unwanted paragraphs,
so I'd like to get a list of all of them and see if we can't find a
way to make this work across the board.
