Some commands have a table of sub-commands. With a minor adjustments, complete_cmdv() is able to provide auto-completion for sub-commands (it's just about passing the table of commands instead of taking the global one). We rename this function into complete_subcmd() and implement complete_cmdv() as a wrapper around complete_subcmdv().
