>>> import locale
>>> locale.setlocale(locale.LC_ALL, ('de_DE', 'UTF-8'))
'de_DE.UTF-8'
>>> locale.currency(1345345345352.22, international=True)
'1345345345352,22 EUR '

Expected: '1345345345352,22 EUR'

This isn't just de_DE locale, but any locale that puts currency symbol after the value. This issue is even "acknowledged" in the test. I'd think that appropriate fix would be to .rstrip smb on line Lib/locale.py:282
Alternatively, function return value could be stripped.
