[Rd] is.null(list()) is FALSE ?

[Torsten Hothorn]

On R-1.0.0, debian GNU/Linux, 

R> is.null(list())
FALSE

conflicts with the help for ?is.null:

Examples:

     is.null(list())    # TRUE (not so in S)
     is.null(integer(0))# F
     is.null(logical(0))# F
     as.null(list(a=1,b='c'))

and, I would like is.null(list()) to be TRUE :-)
