[ESS] how to disable bolding of command line text

[Pierre Kleiber]

I have upgraded both emacs to 23.1.1 and ess to 5.7.1 and find that now when 
commands are entered in the command (iESS) buffer the text is automatically 
bolded. This is annoying because the bold characters are blurry to my old eyes. 
I've been unable to find a way to disable this behavior. I put this in my .emacs 
file:
   (setq font-lock-maximum-decoration '((ess-mode . 1)))
following advice in the emacs manual, but it had no effect. Does anyone have 
other suggestions?

Thanks.
