[issue3140] str.format("{0:n}") poss. bug with setlocale()

[Mark Summerfield]

New submission from Mark Summerfield <mark at qtrac.eu>:

Python 30b1

>>> import locale
>>> locale.setlocale(locale.LC_ALL, "en_US.UTF-8")
'en_US.UTF-8'
>>> for x in
(1234,12345,123456,1234567,12345678,123456789,1234567890,12345678900):
	print("[{0:>20n}]".format(x))

	
[                1,234]
[               12,345]
[              123,456]
[             1,234,567]
[            12,345,678]
[           123,456,789]
[          1,234,567,890]
[         12,345,678,900]

I expected that the commas would not increase the width, but maybe this
was the intended behaviour?
