You must mean __trunc__ to support builtin.trunc(), since
builtin.round no longer calls __round__ in 2.6. The other 3 methods
specified by PEP 3141 aren't strictly necessary for 2.6, but they will
be needed for 3.0. I'd rather not make the two versions of Decimal
gratuitously different, so this patch puts them in the 2.6 version
too. That's basically all of the changes in this patch, so I'm not
sure exactly what you're objecting to. Could you be more precise?
