The ">" alignment flag to format() is not right aligning numbers
properly on trunk and the py3k branch:

>>> format(0x1234, "+#08x")
'+0x01234'
>>> format(0x1234, "0=+#8x")
'+0x01234'
>>> format(0x1234, "0>+#8x")
'+0x01234'

That last one should be:
>>> format(0x1234, "0>+#8x")
'0+0x1234'

The intended behaviour of ">" is more obviously correct when you
consider a leading space instead of a leading zero:

>>> format(0x1234, " >+#8x")
' +0x1234'

This is only an error on the development versions - the behaviour is
correct on the 2.6 and 3.1 maintenance branches.

Is this the same problem as in issue 6902?

I think they're the same issue, relating to what happens if there's an
alignment specifier supplied along with '0'. I'm planning on working on
this issue this weekend and I'll verify if it's the same problem.

Just checked, and yep, it's a duplicate of 6902 - the problem does
indeed go away if I use a different formatting character.
