Summary: strptime %U broken

Initial Comment:
Python 2.4.1 (#1, May 16 2005, 15:19:29)
[GCC 4.0.0 20050512 (Red Hat 4.0.0-5)] on linux2

>>> from time import strptime
>>> strptime('2006-53-0', '%Y-%U-%w')
(2006, 12, 31, 0, 0, 0, 6, 365, -1)
>>> strptime('2007-00-0', '%Y-%U-%w')
(2006, 12, 24, 0, 0, 0, 6, -7, -1)
>>> strptime('2007-01-0', '%Y-%U-%w')

Note that in the above test, Sunday of week 1 and week 2 for 2007 reported the date as 2007-01-07 and Sunday of week 0 was reported as 2006-12-24, not 2006-12-31.  I'm not sure exactly what is correct, but the inconsistencies are bothersome.

Same results on:
Python 2.4.4c1 (#70, Oct 11 2006, 10:59:14) [MSC v.1310 32 bit (Intel)] on win32

I will try to fix this when I can.  Just to warn you, Brian, I really
doubt I will put the effort into backporting this to 2.4.
