It's not displayed by the help system, it is displayed by the demo() 
function.  There wasn't a way to get to it through the help system in 
previous versions, was there?  (If you were running a browser you could 
browse files on the local file system, and you could construct a \url{} 
in a man page, but I don't think there were any links to the demo 
directory generated by R, were there?)
