Describe the bug

I am using the new Walk() feature by @dearchap to generate a tree of supported commands of my tool. This works great.

However, I want to exclude Hidden commands from the output. I can query the Hidden flag and do that, however, subcommands of a hidden command show up anyway.

To reproduce

func Tree(cmd *cli.Command) error {
	max := 20

	cmd.Walk(func(cmd *cli.Command) error {
		path := cmd.Path()
		command := path[len(path)-1]

		if len(path) == 1 || command == "help" || cmd.Hidden {
			return nil
		}

		indent := strings.Repeat("  ", len(path[1:])-1)
		space := strings.Repeat(" ", max-(len(command)+len(indent)))

		fmt.Printf("%s%s %s - %s\n", indent, command, space, cmd.Usage)

		return nil
	})

	return nil
}

Observed behavior

This prints this at the end:

[..]
version               - show esctl version information
debug                 - developer only
help-jsonpath         - show jsonpath help
  bash                - Output bash completion script
  zsh                 - Output zsh completion script
  fish                - Output fish completion script
  pwsh                - Output pwsh completion script

So, the command completion has been skipped, but its subcommands are not hidden and show up anyway.

Expected behavior

I'd like to have a way to check the parent of a cmd if it's hidden, eg:

if len(path) == 1 || command == "help" || cmd.Hidden || cmd.Parent.Hidden {
	return nil
}

And many thanks for the cool Walk() and Path() feature, I'm loving it!
