I agree. Forcing them to all use the 'progname' module is overkill.

This won't work: A program cannot define program_name itself _and_
use the 'progname' module: The 'progname' module will not work if
set_program_name is never called.

Rather, the 'progname' module is an alternative approach to
"char *program_name". One that works with shared libraries in particular.
