Bug: iptables -L and -Z at the same time now refuses other options

Hi all,

I don't have a Bugzilla account so would someone mind logging this bug
for me?

I just updated iptables and now this command fails:

  $ iptables -L -v -n -x -Z
  iptables v1.8.11 (legacy): Illegal option `--numeric' with this command

The manpage says that it is valid to use -Z with -L, which displays the
values before zeroing them.  However the latest iptables release doesn't
allow you to specify -n if you are including -Z, which means if you
want to display AND zero the counters at the same time, you can't have
the raw numeric values shown.

It works fine if you omit -Z but then you end up losing precision,
having to run two commands (one to show the counters and then another
one to zero them, with any change in the counters occurring between the
two commands lost).

If you remove the -n option, it then also complains about -x:

  $ iptables -L -v -x -Z
  iptables v1.8.11 (legacy): Illegal option `--exact' with this command

This used to work so hopefully it's a small bug that can be easily
fixed.  It looks like while -L and -Z are still permitted at the same
time, most of the options for -L are now being incorrectly refused if -Z
is also specified.

Many thanks,
Adam.
