[ESS] Disable font-lock-mode in .emacs

[Sebastian Schubert]

Hi,

disabling the font-lock-mode in the inferior ESS buffer increases the
performance considerably. I tried disabling it only for the inferior ESS
mode in the .emacs but was unsuccessful. I tried

(remove-hook 'inferior-ess-mode-hook `turn-on-font-lock)
(add-hook 'inferior-ess-mode-hook (lambda () (font-lock-mode 0)) t)

While I think only the first line should be necessary the first line
should not hurt...

Any idea what I can do? I'm at a GNU Emacs 24.3.1 with ESS 13.09.

Thank you,
Sebastian
