[Bug fortran/41152] New: Spurious diagnostic "Extraneous characters in format"

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

gfortran now warns for trailing characters in format statements. However, it
does not properly work as the following test case (extracted from FLEUR,
www.flapw.de) shows:

 7182 FORMAT (a3)
                      1
Warning: Extraneous characters in format at (1)

Due to committal:

        * io.c : added variable to store original len of fmt
        * io.c (check_format): Consume H items using next_char
        in both modes to handle consecutive single quotes.
        Test for extra characters in fmt, issue warning.

Test case:
      SUBROUTINE rw_inp()
      CHARACTER(len=100) :: line

      READ(*,FMT="(4x,a)") line
 7182 FORMAT (a3)
 7130 FORMAT (i3)
      END SUBROUTINE rw_inp
