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.
Now Ken tells me that we don't want to do this. See http://www.winehq.org/pipermail/wine-devel/2009-November/080062.html . He says that instead, if you want Wine to appear in another language, you should set LC_MESSAGES.
