[Bug fortran/29819] New: Error/warning message should ignore comments for "1" in %C output

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

If one compiles with -std=f95 the following program:
-----------------------
! { dg-do compile }
! { dg-options "-std=f2003" }
! Check whether empty contains are allowd
module x
 contains
end module x ! { dg-error "CONTAINS statement must be followed by a FUNCTION or
SUBROUTINE statement" }

program y
  contains
end program y ! { dg-error "CONTAINS statement must be followed by a FUNCTION
or SUBROUTINE statement" }
------------------

The location shown is not really helpful:
--------------------------
contains.f90:6:

nt" }
    1
Error: Fortran 2008: CONTAINS statement must be followed by a FUNCTION or
SUBROUTINE statement at (1).
contains.f90:10:

nt" }
    1
--------------------------

Expected:
- String is not trimmed that early (only 5 characters shown)
- 1 is not under a comment

Example for a better output:

end module x ! { dg-error "CONTAINS statement must
           1

or as ifort (the "^" is below the "e" of "end module"):
end module x ! { dg-error "CONTAINS statement must be followed by a FUNCTION or
SUBROUTINE statement" }
