You are right. I managed to reproduce the problem with a test. It only occurs when a fix is applied.

Also, I figured out that the refactoring reads in the file using `open(file, 'r')`, which basically transforms all line-endings to LF regardless the used line-endings. I think I fixed the problem, looking forward to receiving feedback 😬
