Andrew Sheinberg posted about this yesterday

  If you are working locally on a Windows machine and you create a test file
  make sure that the line endings are in Unix form.
   
  Depending on the editor you use, hitting "enter" on a Windows machine to
  create a newline corresponds to a carriage return, \r\n. This is really
  two different ascii characters as opposed to a newline which is just, \n.
   
  If you are using Sublime you can fix this by going to View -> Line Endings
  -> Unix.

An alternative is to write a VERY short C program that
copies the standard input to the standard output but
does not copy carriage returns (i.e., '\r' in C).  K&R
Chapter 1 contains nearly all of the code.  You can use
this filter to remove the returns from your test cases.

Another alternative is to do your development in Linux,
not Windows.
