The issue here is that when you check out on Windows using Git, it will rewrite all of the line endings from Unix to Windows. This breaks the FormSourceAnalyzer. We need to make it more robust, but the correct thing here isn't to just change the lines from Unix to Windows line endings as that just breaks it for those of us using macOS and Linux. Instead, it should be robust to either line ending.
