Links inside styled contexts aren't recognized

[hostilefork]

If I call markdown on "*[hostilefork](http://hostilefork.com)*" I get"<em>[foo](http://example.com)</em>"

Expected the inner link to be processed.

Similar problems happen if the outer style is done with double asterisks for bold style, etc. Backticks should not recognize markdown inside.

(Note: I assume it's probably obvious...but what happens here is that text is captured without then recursing. So what I'm doing as a workaround is taking context that capture into text, which then put text into the HTML, and replacing it with either xml? [markdown/xml text] [markdown text]...with a recursion-safe modification to markdown. But I'm probably not doing it how you'd want it done.)
