incdec: Idea for point moving when changing from positive to negative

If we change between negative and positive numbers, point moves:

    $ test 12 0
               ^
    _decrement_

    $ test 12 -1
               ^

I think point should instead be

    $ test 12 -1
                ^

Not sure that we should be moving point when changing from negative to
positive, though.
