Not sure why this line is changed, probably IDE settings related:
- All line endings should be unix (\n), so not windows (\r\n) or mac (\r). Git should already be forcing that through the .gitattributes file.
- All indentation should be 4 spaces, never a tab (\t).

I 'll fix these issues while merging the request. Please correct your IDE settings for future submissions :)
