[ESS] synthax higlighting \Sexpr in .Rnw files

[Emanuel Heitlinger]

nrow looks best to me.
I will use this in future. Thanks!

Now that my .Rnw files look sane again, the motivation to solve the
problem in emacs is somehow smaller.
I experimented with

describe-variable RET font-latex-match-math-command RET

which resulted in:

 font-latex-match-math-command's value is
"\\\\\\(\\(?:\\(?:ensuremath\\)\\)\\>\\)"

  Automatically becomes buffer-local when set in any fashion.

Documentation:
Not documented as a variable.

wouldn't it be possible to put some "not-inside-Sexpr" regex around
this and reset this variable in a Rnw-mode-hook?
I would need some help on this lisp regexp...
Or is it the wrong approach/variable?

I also experimented with
(add-to-list 'LaTeX-verbatim-macros "Sexpr") without success...
