hex(-5) => Futurewarning: ugh, can't we have a better hex than '-'[:n<0]+hex(abs(n)) ??

>>> hex(-5)
__main__:1: FutureWarning: hex()/oct() of negative int will return a signed string in Python 2.4
and up
'0xfffffffb'
>>> hex(-5)
'0xfffffffb'
>>> hex(-5L)
'-0x5L'
That is sooo ugly. I suppose it is for a backwards compatible repr, but couldn't we
at least have hex(n, newformat=False) so that we can do
hex(-5, True) => 1xb # 1x signals an arbitrary number of prefixed f's
hex( 5, True) => 0x5
and have int() and long() recognize these?
Also would need a variant of %x and %X for formatting with the % operator.
