I cannot replicate this. I included this in a simple document with

\documentclass[a4paper]{article}
\begin{document}
<<>>=
...
@
\end{document}

When I use the version above, _no_ comment shows up (as expected). When I 
use <<keep.source=TRUE>>= then _all_ comments show up (as expected).

This is R 2.13.1 on Debian/GNU Linux.
