Markdown 1.0.2b4 Performance Drop

[Allan Odgaard]

I was recently made aware of the the Markdown 1.0.2 beta 4 and  
naturally downloaded it in great anticipation, as I am a big fan of  
Markdown :)

Though I did notice a significant performance drop: The TextMate  
manual is 3,000 lines (173 KB) and previously took 4-5 seconds to  
convert to HTML (measuring only time spent by `Markdown.pl`.) With  
the new version this has increased to almost 30 seconds.

Another problem is the new handling of embedded HTML (as block level  
tags.) Take this example:

	<div>
		<div id="foo">
		</div>
	</div>

The markup for that ends up as:

	<div>
	    <div id="foo">
	    </div>

	<p></div></p>
