[ESS-bugs] ess-mode 12.09 [rev. 5167 (2012-09-24)]; highlighting logical variables

[Stefano Conti]

I'm now writing from my home laptop, where I've got the most up-to-date 
version of Emacs (i.e. 24.2.1) and ESS (i.e. 12.09): I observe no 
problem with font locking; everything looks to behave as expected.

I didn't pay attention myself to the fact that the Emacs version I got 
at work -- where I normally write from during work-days -- is somewhat 
outdated (version 22.1.7).  Do you reckon this could this be at the root 
of the problem?
