As far as I have seen it, only minor changes had to be done after the
2to3.py script had been run. These had been mostly related to subprocess
output (mostly for parsing git output). Since you probably don't parse
output of a subprocess in these refactorings, I don't think you would
have any problems at all. This should go into a branch, so we can easily
merge in all changes we make.
