It's amazing that the Python maintainers think it's a good idea to
randomly break everyone's stuff in this way.  Just imagine what would
happen if glibc one day started printing a warning like this on stderr
if users had a locale they didn't approve of.

I applied this to master, branch-2.7, and branch-2.6.

Thanks,
