Internally, -0 is used as a short option to represent --line-numbers. This
causes confusion, however, when using --line-numbers with a command which
does not support it. For instance:
# /usr/local/iptables/sbin/ip6tables -S --line-numbers
ip6tables v1.4.20: Illegal option `-0' with this command
Fix this by enabling and documenting -0 as a short option for --line-numbers.
