That's what the spec says. However, that's not how setuptools worked for
me a week ago and is now.

'1.0-dev' is considered earlier than '1.0' as is '1.0dev':

>>> from pkg_resources import parse_version
>>> parse_version('1.0dev')
('00000001', '*@', '*final')
>>> parse_version('1.0-dev')
('00000001', '*@', '*final')
>>> parse_version('1.0-r123')
('00000001', '*final-', '*r', '00000123', '*final')
>>> parse_version('1.0r123')
('00000001', '*r', '00000123', '*final')
>>> parse_version('1.0a1')
('00000001', '*a', '00000001', '*final')
>>> parse_version('1.0-a1')
('00000001', '*a', '00000001', '*final')
>>> parse_version('1.0')
('00000001', '*final')
