[Python-Dev] Negated hex/oct constants (SF #660455)

[Tim Peters]

Ooh!  We can't blame this one on the peephole opt, right?  In current CVS:

>>> -int("0xffffffff", 0) # and this does not generate a wng
1
>>> int("-0xffffffff", 0)
-4294967295L
>>>

As in the tail end of the last msg, the base specifier makes a big
difference here too:

>>> -int("ffffffff", 16)
-4294967295L
>>> int("-ffffffff", 16)
-4294967295L
>>>
