[Rd] dump/source problem with hclust object (PR#4361)

[Liaw, Andy]

?dump says:

Details:

     At present the implementation of `dump' is very incomplete and it
     really only works for functions and simple vectors.

     [...]

     The function `save' is designed to be used for transporting R data
     between machines.

So I guess, technically, this is not a bug, nor is your other example.  (An
"hclust" object is hardly a simple vector.)
