    Fortran  : rejected f0.d edit descriptor PR96436

    Zero length f format descriptors are valid for Fortran 95 and
    later.  For g format descriptors from Fortran 2008 and later.
    Finally for D, E, EN and ES for Fortran 2018 and later.

            * io/format.c (parse_format_list):  Add new local variable
            "standard" to hold the required standard to check. If the
            format width is zero select standard depending on descriptor.
            Call notification_std using the new standard variable.
