From http://bugs.python.org/issue18738:

Actually the problem not only in IntEnum, but in any in subclass.

Currently for empty format specifier int.format(x, '') returns str(x). But str can be overloaded in a subclass. I think that for less surprising we can extend this behavior for format specifier with the width, the alignment and the fill character but without the type char. I.e. int.format(x. '<10') should return same as format(str(x), '<10').

The question remains what to do with the sign option. And with the '=' alignment.
