docs: Sets whether arguments on the command line that resemble an option should be treated as positional parameters.
  The default is {@code false}.
  <p>The specified setting will be registered with this {@code CommandLine} and the full hierarchy of its
  subcommands and nested sub-subcommands <em>at the moment this method is called</em>. Subcommands added
  later will have the default setting. To ensure a setting is applied to all
  subcommands, call the setter last, after adding subcommands.</p>
  @param newValue the new setting. When {@code true}, arguments on the command line that resemble an option should be treated as positional parameters.
  @return this {@code CommandLine} object, to allow method chaining
