Comment:

 I've implemented markdown processing in a branch, and just discovered this
 ticket.  Is there a reason that CPP is preserved in the comment part of a
 literate file?  Shouldn't it be that CPP is only preserved when it shows
 up in either a birdtrack or \begin{code} ... \end{code} block?  Preserving
 it in the comment portion of a literate program seems akin to processing
 CPP that is in the comments of a non-literate file; I would normally
 expect commented-out CPP to not be run.
