"""
Fixer for removing any of these lines:
from __future__ import with_statement
from __future__ import nested_scopes
from __future__ import generators
The reason is that __future__ imports like these are required to be the first
line of code (after docstrings) on Python 2.6+, which can get in the way.
These imports are always enabled in Python 2.6+, which is the minimum sane
version to target for Py2/3 compatibility.
