Summary: broken error handling in unicode-escape

Initial Comment:
Error handling for decoding unicode-escape encoded
string seems the be slightly broken:

Python 2.2 (#2, Mar  1 2002, 17:32:59) 
[GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on 
linux2
Type "help", "copyright", "credits" or "license" for 
more information.
>>> "\N{foo}xx".decode("unicode-
escape", "ignore")      
u'\x08xx'
>>> "\".decode("unicode-escape")                    
u'\\U082a74f8'

Applied in Objects/unicodeobject.c revision 2.124.6.6, thanks!

I also added the cases from the report to test_unicode.py
revision 1.47.6.1.

These changes will need to go onto the trunk, at some future
point.

Assigned to Martin. I don't have time for this the next two weeks.

This falls in the "doctor, it hurts when I do this"
category, and it is not a regression over 2.1.x, so I don't
think it is critical to fix for 2.2.

Agree that looks nasty.  Any chance of a quick fix from Marc
or Martin?
