Files with \n only as the line separator are produced by Mac OS X, and
other unix/linux/*nix OS applications.

Files with \r\n as the line separator are produced by Windows.

Files with \r only as the line separator are produced by MacOS 9
applications, or confused programs/programmers.

I'm surprised that you have a file with really just \r.

Oops, spoke too soon. The file seems to have just '\r' at the end of each
line (Unix vs. Windows?).
