That's interesting, and because the output is valid, it's probably
better than what Markdown.pl currently generates.

I've been thinking that a better solution for input like that
would be to generate markup like this:

    <em>Some <strong>strange</strong></em><strong> emphasis</strong>

Which is more of a "do what I mean" solution. However, I've given
no thought whatsoever to how this would be done algorithmically.
