Nope. Core Foundation returns en_US.UTF-8, no matter what I set LANG to.
(That's the current locale on my system, as set in System Preferences.app.)

I found this line several times in the +nls log:

trace:nls:LOCALE_Init setting lcid_LC_MESSAGES to 'en'

which indicates that the real reason LANG doesn't appear to affect locale is
that Wine loads strings based off of the LC_MESSAGES setting, which is set to
the user's default language on Mac OS.

I know how to fix this now. What we want to do is avoid overriding LC_MESSAGES
if there was a LANG variable to begin with.
