Niels M=F6ller contributed a bit invert, I'd managed to forget about it
until recently. It'll probably go in the next release.
Add a bit-block copy to your list too, a sort of combination extract
and insert perhaps.

We've probably already got problems on non 2s complement binary

It could apply to mpf without much trouble, if we thought there was a
use for it. In theory it could apply to mpq too, but that's likely to
be even less useful.
