And I appear to have sent the one without the usage comments at the top.
Here they are:

 * USAGE:
 *    $ gcc -g maptest.c
 *    $ ./a.out z
 *    $ hexdump -C z.NEW
 *
 * Notice the block of zero byte records appearing within
 * the output.
 *
 * Run with a second argument:
 *
 *    $ ./a.out z 1
 *    $ hexdump -C z.NEW
 *
 * No more zeros!
