What is this output from 2to3 supposed to mean?
  $ cat mysub.py
  isinstance (3, (int,float))
  $ 2to3 -f isinstance mysub.py
  RefactoringTool: No changes to mysub.py
  RefactoringTool: Files that need to be modified:
  RefactoringTool: mysub.py
Why does mysub.py need to be modified, and how?

Bleh. Who came up with this user interface?

I call confusing output like this a UI bug. But after playing around with
various small files, it *seems* to me that the "Files that need to be
modified" actually means "Files that include something that a fixer cares
about, whether or not it gets modified" (in this case, isinstance).
