        Under certain circumstances, some versions of diff do not correctly
        detect a missing new-line at the end of the file. As a result, patches
        created by such diff programs do not record incomplete lines
        correctly. This option adds support for applying such patches by
        working around this bug.

        Report progress to stderr. By default, only a message about the
        current patch being applied will be printed. This option will cause
        additional information to be reported.
