For all who want to save time typing while testing, I've already 
implemented the forceadd support in the ipset-bash_completion code 
available here:


As it's set to enable the feature from ipset v6.21+, you need to either 
bump the ipset version, or just change line 886 in my code from:

  if ((ips_version[0] == 6 && ips_version[1] >= 21)); then

to:

  if ((ips_version[0] == 6 && ips_version[1] >= 20)); then

happy testing :)
