[ESS] Weird behaviour of assignment symbols with Emacs-24.1 (and ESS 12.04-4)

[John Maindonald]

Hi Vincent -
Maybe it does have to do with color settings, on some part of my system.
I have however no idea where to look.  Until light dawns, I will stick with the
Emacs 23.4 build.  

Thanks anyway
John.
