Here is the code for a filter that should do the trick.

#! /usr/local/bin/perl -w
use IO::File;

while ($string = <STDIN>)
{
   chomp($string);
   STDOUT->print("$string\r\n");
}

Of course, this begs the question of why, once you have a file that is not contaminated by newlines you would want to add them for the sake of Notepad, but I will leave that discussion to others... :-)
