As far as I know, that's not what ":comments" is for. It just references
which chunk it came from.

I proposed this very feature, see
http://eschulte.github.com/babel-dev/PROPOSED-tangle-entire-org-mode-file-in-comments.html 
and the associated gmane thread linked from there...

I assume you know about the code export features that could generate very
nice annotated code in HTML or PDF.
