[issue19111] 2to3 should remove from future_builtins import *

[Milan Oberkirch]

Milan Oberkirch added the comment:

Here is a simple patch that would solve this issue.
The new fixer 'future_builtins' removes `from future_builtins import foo` statements if they aren't nested in other constructs (try-except, classes, ...) and replaces them with `pass` otherwise.
