Summary: _PyEval_SliceIndex vs NULL

Initial Comment:
_PyEval_SliceIndex goes out of its way to say 
everything's fine when passed a NULL pointer, but 
leaves the output *pi untouched in that case.  But, 
AFAICT, it doesn't make sense to call this routine 
with a NULL pointer, and nobody does.  So it should 
assert that v is not NULL.  Hold for 2.3 "just in 
case".

Get some sleep. :-)

_PyEval_SliceIndex() is called by apply_slice() which can be
called by the SLICE opcode with v and/or w equal to NULL.
