Different platforms have different line-break conventions. \n is a line
feed, while \r is a carriage return (these names date from typewriters,
I believe!)
I think that \r\n is the standard way to separate header fields in HTTP
and SMTP, but maybe it's just the most interoperable way. Everyone I
know does it, so I'm just being a sheep...
