It was observed in
[http://groups.google.com/d/topic/sage-support/OEHb5aIjBIQ/discussion this
sage-support thread] that Python new-style format specifiers for Sage
Integers don't work. The solution is easy: Equip Integer with a
`__format__` method that simply converts the Sage Integer to a Python int
and then calls the `__format__` method on that. Given that converting a
GMP int to a Python int should be much cheaper than converting either to a
string, I don't expect much of a performance penalty, and implementing the
whole Format mini-language again seems a waste of effort.
