[ESS] Colors in noweb mode

[Kasper Daniel Hansen]

Quick questions:

(1) are are using emacs in a terminal (-nw) or in an Xwindow?
(2) when you move around in noweb mode, does the modeline change
appropriately when you move from a latex chunk to an R chunk and back
again?

This is not too helpful, but I would consider upgrading Emacs.  In my
experience the newer Emacs (version 22 or 23) are much better at
handling this stuff (but this is purely anecdotal)
