Feature Request: Multiline Comments

Hello,
Is it possible to extend the R lexer/parser to include multiline comments like
/*
acomment

*/
?
This way I can integrate emacs org-mode with my R code, so that I can
have a table of contents,
section folding, html-output of source etc.

e.g
/*
* Display Code
*/
#+BEGIN_SRC R

foo <- function(...){
stuff
}

#+end_src

and so on .

Thanks
