Working on it. In read_sf we have this:

      /*  Short circuit the read if a comma is found during numeric input.
          The flag is set to zero during character reads so that commas in
          strings are not ignored  */
      else if (q == ',')
        if (dtp->u.p.sf_read_comma == 1)
          {
            seen_comma = 1;
            notify_std (&dtp->common, GFC_STD_GNU,
                        "Comma in formatted numeric read.");
            break;
          }

and it does give an error when using -std=f95. No such code for
read_internal_sf.
