 * This program is a simple filter to fix some of the problems with the
 * windows 3.0 "Generic / Text Only" printer driver.  The program fixes the
 * following two bugs:
 *
 *	1: When printing justified paragraphs, the driver prints zillions
 *	   of one-character lines.  This collapes them into one line
 *	2: The driver ends lines with a line-feed/carriage return pair
 *	   instead of the other way around.
