-(0.0) gets parsed as -0.0

[kmod]

I haven't looked into this so I'm not sure where there happens, but Pyston ends up getting the same ast for either text. the cpython parser says the first is a unaryop on 0.0, and the second is the float -0.0.

Doesn't seem like a big deal since it's probably only observable if you are doing direct ast manipulation.
