Bug Description

The man page refers to sub-uids and sub-gids but those don't take any "-" between sub and [ug]ids. The help message conforms to what the command accepts though.

$ man usermod | grep -F -- -sub
       -v, --add-sub-uids FIRST-LAST
       -V, --del-sub-uids FIRST-LAST
           This option may be specified multiple times to remove multiple ranges to a users account. When both --del-sub-uids and --add-sub-uids are specified remove of all subordinate uid ranges happens before any
       -w, --add-sub-gids FIRST-LAST
       -W, --del-sub-gids FIRST-LAST
           This option may be specified multiple times to remove multiple ranges to a users account. When both --del-sub-gids and --add-sub-gids are specified remove of all subordinate gid ranges happens before any

$ usermod --help | grep -F -- -sub
  -v, --add-subuids FIRST-LAST add range of subordinate uids
  -V, --del-subuids FIRST-LAST remvoe range of subordinate uids
  -w, --add-subgids FIRST-LAST add range of subordinate gids
  -W, --del-subgids FIRST-LAST remvoe range of subordinate gids

Right, my bad, sorry.

I tried following nacc's suggestions (he brought it over IRC) because I, unkowningly, did a really terrible job last time.

Hopefully, this commit is way more understandable and (again, hopefully), I did everything well.

Please share if you see something I missed.

Thanks!
