Remove [command [command options]] from help text if there are no sub commands #1921

Hi there, I think it would help readability a lot if cli/v3 can check for subcommands first before printing the help of a command.

For example, right now this is the help that I get:

NAME:
   app cmd1 cmd2 - does something cool

USAGE:
   app cmd1 cmd2 [command [command options]] <myArgUsage>

OPTIONS:
   --flag value  (default: 1)
   --help, -h     show help (default: false)

Note that cmd2 has no sub-commands which makes it distracting from reading and understanding the USAGE. So what I'd love to instead see is:

NAME:
   app cmd1 cmd2 - does something cool

USAGE:
   app cmd1 cmd2 <myArgUsage>

OPTIONS:
   --flag value  (default: 1)
   --help, -h     show help (default: false)

@marwan-at-work want to make a PR for me to review for this ?
