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).
