Recently, there was a discussion about the same topic. See
http://thread.gmane.org/gmane.emacs.devel/118789

We will try to apply LC_MESSAGES and LC_NUMERIC selectively. However,
givent that there is already feature freeze of Emacs 23.2, I cannot
promise we will be able to put it into that release. It depends, whether
the needed changes are small enough to ensure that there won't be
collateral damages.
