R - folding multi-line comments

It would be great if the R lexer could support folding multi-line comments in R.  This is particularly useful with function headers.  Ideally, when the comments are folded only the top-most line shows (i.e. the name of the function).  Here's an example of a function header using Roxygen-style documentation. 

#' Test Function

#' 

#' My test function description

#'

#' @param firstParam  first parameter description

#' @param secondParam second parameter description

#'

#' @return  what the function returns

#' @note some notes here

TestFunction = function( ... )
