 Shorthand for `--with-default cmd-default --require-services` *flag subcommand...*.  That is, if the current service set is empty, it defaults to the `cmd-default` target, if defined.  The number of services is then verified with `--require-services` before executing *subcommand*.  This makes it easy to define new subcommands that work on a default container or group of containers.  (For example, the `doco sh` command is defined as `doco cmd 1 exec bash "$@"` -- i.e., it runs on exactly one service, defaulting to the `cmd-default` group.)
