it works for some of the markdown, but there are some things it doesn't help. 
basically, it stops cow barfing if there are characters like & < > when it 
parses the input; but cow then escapes these which means the js in the page 
that parses the markdown can't recognise them.

eg., `<&>` in a markdown fragment either causes cow to barf (parse error), or 
if surrounded by CDATA cow turns it into `&lt;&amp;&gt;` in the html returned 
to the browser, so the js then renders it as the corresponding string literal 
(in html, "&amp;lt;&amp;amp;&amp;gt;") in a monospaced font. 

the best i can think of is some way to explicitly tell cow to not parse a chunk 
of input and leave it "raw". or else i'll have to revert to serving fragments 
out of files and not use cow at all.
