I think the right thing to do is change the set of filenames that _ApplyEdits()
operates on below. It doesn't make sense to pass .h files to the compiler
dispatcher.

Yes, that's much cleaner. Done.

     filenames = [f for f in filenames
                  if os.path.splitext(f)[1] in extensions]
   dispatcher = _CompilerDispatcher(argv[0], argv[1], filenames)
