Command-line option -L not shown with usage message

Summary

When named detects a problem with command-line options and prints usage information, it doesn't show the -L option.

BIND version used

9.16.13

Steps to reproduce

Run "named -L"

What is the current bug behavior?

BIND outputs a usage message like this:

usage: named [-4|-6] [-c conffile] [-d debuglevel] [-E engine] [-f|-g]
             [-n number_of_cpus] [-p port] [-s] [-S sockets] [-t chrootdir]
             [-u username] [-U listeners] [-m {usage|trace|record|size|mctx}]
usage: named [-v|-V]
named: option '-L' requires an argument

What is the expected correct behavior?

BIND should print usage about the -L option along with the other options it understands.
