Describe the bug

When I make a command with only one subcommand and hide the help command my subcommand is not displayed.
My guess is that since a command and a subcommand is the "same", it always hide the command list when it's fewer than one item there, because it assumes it is the help-command.

To reproduce

package main

import (
	"log"
	"os"

	"github.com/urfave/cli/v2"
)

func main() {
	app := &cli.App{
		Name: "hello",
		Commands: []*cli.Command{
			{
				Name: "world",
				HideHelpCommand: true,
				Subcommands: []*cli.Command{
					{
						Name: "welcome",
					},	
				},
			},
		},
	}

	if err := app.Run(os.Args); err != nil {
		log.Fatal(err)
	}
}

Observed behavior

./nais p password -h
NAME:
   nais postgres password - Administrate Postgres password

USAGE:
   nais postgres password [command options] [arguments...]

OPTIONS:
   --help, -h  show help

Expected behavior

./nais p password -h
NAME:
   nais postgres password - Administrate Postgres password

USAGE:
   nais postgres password command [command options] [arguments...]

COMMANDS:
   rotate

OPTIONS:
   --help, -h  show help

Additional context

If I enable HideHelpCommand for the specific command (not the subcommand) it works.

@Kyrremann Thanks for reporting this. Can you set HideHelpCommand at the App level and see if that works for you ?

[Kyrre Havik]

I have already set that value to true at the App level, no change for me in my original code (did not try it in the reproduce example).

For now my solution is just to show the help-command, it's not a big deal for us.

PS: This is my code where I'm using this library, it's a big PR where I change from cobra/viper to this one: nais/cli#209

[dearchap]

@Kyrremann Can you try the fix in the PR ? Thanks

[Kyrre Havik]

That fixed it!
