+       What are considered whitespace errors is controlled by `core.whitespace`
        configuration.  By default, trailing whitespaces (including
        lines that solely consist of whitespaces) and a space character
        that is immediately followed by a tab character inside the
        initial indent of the line are considered whitespace errors.
