and 4 separate imports seemed better style to me than any other way to break it up.

I don't necessarily agree. Adding parentheses is better IMHO:

from __future__ import (absolute_import, division, print_function,
                        unicode_literals)

I'd like to get some other feedback on that before you have to re-write your sed command though 😄

Given the restriction that __future__ come first, I had no idea it could be broken up. For consistency with other imports though, where we don't currently enforce that each "from x import y" has only one "y", I think @pelson's suggestion is preferable.

Forcibly replaced the old commit with a new one using pelson's suggestion. Also caught a few files I missed last time.
