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

[Stefano Conti]

Hi Viatlie,

Thank you for your follow-up.

I had already apologised to Martin -- and now to you as well -- regarding my poor choice of wording, due to me being genuinely unsure how I shoul;d have described the problem.

I have not reported any other problem regarding TRUE / FALSE statements; these aren't highlighted at all.  Following your instructions on a FALSE statement I obtain no indication as to its face:

== START ==
  character: L (76, #o114, #x4c, U+004C)
    charset: ascii (ASCII (ISO646 IRV))
 code point: #x4C
     syntax: w which means: word
   category: a:ASCII graphic characters 32-126 (ISO646 IRV:1983[4/0]) l:Latin
buffer code: #x4C
  file code: #x4C (encoded by coding system undecided-unix)
    display: by this font (glyph code)
     -Adobe-Courier-Medium-R-Normal--12-120-75-75-M-70-ISO8859-1 (#x4C)

There are text properties here:
  fontified            t
== END ==

The only font setting command I have in my .emacs file is

(setq font-lock-maximum-decoration t)

which shouldn't interfere with the font locking issue I've notice; that is unless I'm mistaken.

Hope the above helps; thank you again, cheers,

Stefano
