If I want a program to duplicate the line, and sometimes it truncates it
then that program does not work correctly.  For every programming
problem there is a solution that is short, elegant and wrong.

Except that sometimes it does not duplicate the output correctly.

The program has a bug in it - to whit whenever an input line is longer
than 512 bytes, the output is incorrect.
