I've faced the same error. In my case, issue was caused by EOL (End of line) Format. My notepad ++ used LF (Old Mac) Format by default (don't know why).

I solved the issue by converting EOL to Windows Format:

Edit -> EOL Conversion -> Windows Format

Default EOL Format in notepad ++ can be set:

"Settings" -> "Preferences" -> "New Document/Default Directory" then select "Windows" (if you are Windows user offcourse :))

Hope this will help someone.
