Thanks!

I'm still interested how to read comments, if you happen to know the 
answer.  I have other ideas besides the code->html.

Given what I know now, I'd call read-syntax, and use the 'position' and 
'span' properties of the syntax objects to go back over the input 
looking in the "holes" for comments.  A little hacky maybe, but it at 
least I'd reuse the reader.
