[ESS] transient mark mode

[William Knebel]

Our group uses emacs+ess to run R on a mac osx server (10.5.4). I have
an unusual issue between two ESS settings.  We standardly set

 transient-mark-mode t

When I use the above setting with

ess-eval-visibly-p nil

the text in emacs get highlighted appropriately use C-x space
and gets submitted properly using C-x c C-x r but the text in the
emacs buffer satys highlighted as though it was never submitted. Is
this an interaction between these two options.  I would to be able to
use these together. We are using R-2.7.1 and ess 5.3.7.
