Are you on Windows? If so, your double newlines might be \r\n\r\n, 
depending on what editor you used to create the input. Use a hexdump 
program to see what the newlines are in your input file.

Now, you would think that the underlying C stream would do this for you. 
I'm not sure how it works exactly, as I don't use Windows.
