Issues with passthrough

[FatherShawn]

Steps to reproduce

My task is similar to that described in #706.

If I execute: vendor/bin/robo --load-from ./scripts/robo drush -- help sapi-i

Also if I move RoboFile.php to the root of the project and execute: vendor/bin/robo drush -- help sapi-i

Associated robo method:

/**
   * Execute a drush command in the cli container.
   *
   * @param string $drush_command
   *   The command.
   */
  public function drush($drush_command) {
    switch (php_uname('s')) {
      case 'Darwin':
        $this->setMacDockerEnv();
        $this->io()->text("Docker config set as $this->dockerConfig");
        break;

      default:
        $this->io()
          ->error("Unable to determine your operating system.");
    }
    $this->taskExec("docker-compose $this->dockerConfig exec cli /var/www/vendor/bin/drush $drush_command")
      ->printMetadata(FALSE)
      ->printOutput(TRUE)
      ->run();
  }

Expected behavior

I should get the help output for the sapi-i command as shown at https://robo.li/getting-started/#pass-through-arguments

Actual behavior

Too many arguments, expected arguments "command" "drush_command".

drush [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction] [--simulate] [--progress-delay PROGRESS-DELAY] [-D|--define DEFINE] [--] <command> <drush_command>

I thought about this overnight. I’m already using robo to move and maintain certain files and I’m also already using ahoy so another way to solve my specific problem is moving an os.ahoy.yml into place as ahoy.yml using robo to select the source file during setup.

That still leaves pass through not working in robo as documented so leaving this open.
