In the course of investigating issue10092, Georg discovered that the behavior of locale.normalize() on Mac is bad.

Basically, "en_US.UTF-8" is how the "correct" locale string should be spelled on the Mac. If you drop the dash, it fails: which locale.normalize does, so you can't pass the return value of the function to setlocale, even though that's what its documented to be for.

If that isn't clear, this should demonstrate (from /branches/py3k):

Top-2:build pythonbuildbot$ ./python.exe

>>> locale.setlocale(locale.LC_TIME, 'en_US.UTF8')
Traceback (most recent call last):

locale.Error: unsupported locale setting

>>> locale.setlocale(locale.LC_TIME, 'en_US.UTF-8')

The precise same behavior exists on my stock/system Python 2.6, too, fwiw. (Not that it can be fixed on 2.6, but maybe 2.7?)
