[ESS] Code indentation inside an Sweave chunk

[Stephen Eglen]

For the list:
 > 
 > (defun Rnw-mode ()
 >   (require 'ess-noweb)
 >   (noweb-mode)
 >   (if (fboundp 'R-mode)
 >       (setq noweb-default-code-mode 'R-mode)))
 > (add-to-list 'auto-mode-alist '("\\.Rnw\\'" . Rnw-mode))
 > (add-to-list 'auto-mode-alist '("\\.Snw\\'" . Rnw-mode))
 > 
 > (setq reftex-file-extensions
 >       '(("Snw" "Rnw" "nw" "tex" ".tex" ".ltx") ("bib" ".bib")))
 > (setq TeX-file-extensions
 >       '("Snw" "Rnw" "nw" "tex" "sty" "cls" "ltx" "texi" "texinfo"))
 > 

this code is not needed in your .emacs if you are using a recent
version of ESS -- it is now include in ESS.
