[issue30571] Add integer formatting code for fixed-width signed arithmetic (2's complement)

[Lisa Roach]

Lisa Roach added the comment:

I can't see the drawback of being able to format two's complement easily, isn't it more common to represent negative binary numbers in two's complement form? I find the - sign a little odd myself.

I agree with the idea of using "!" with the precision to represent width.
