Title: bin/use2to3 now makes converted files end in exactly one newline

The code quality tester checks for this, and sometimes 2to3 adds extra
newlines, so this keeps the tests passing in Python 3.

This fixes a Python 3 test failure in master. See for example http://reviews.sympy.org/report/agZzeW1weTNyDAsSBFRhc2sY9dgZDA.
