Change Details

As per Utility Syntax Guidelines, accept both forms -l -n and -ln. To do that, anticipate the source for the next option that will be parsed by nextopt(). It's not always *argptr, sometimes it is nextopt_optptr. Rename not_fcnumber() to fcnumber() and adjust its logic in order to avoid introducing a double negative.
