Some messages will have newlines embedded within the message.
The formatter can correctly display these messages by calling:

    format(messages, '[phonegap]');

Options:

  - `args` {Array} of `String` elements to output.
  - `prefix` {String} is prepended to each new line of the output.

Returns:

  {Array} of the correctly formatted args.
