Log message:
        Avoid printing `NONE:0:' in error messages.
        * src/m4.h (m4_error_at_line): New function.
        * src/m4.c (m4_error_at_line): Implement.
        * src/input.c (skip_line, input_init, next_token): Use "", not
        "NONE", for no file, since NONE can be a real file name.
        * src/macro.c (expand_argument): Likewise.
        * src/debug.c (debug_message_prefix, trace_header): Check for
        current file.
        * doc/m4.texinfo (Dnl, M4wrap): Adjust accordingly.
        (Location): Document that synclines and internal message format
        are not impacted by redefining these macros.
        (M4exit): Hint at bug in fatal_error.
        (Answers): Provide workaround to match m4 output.
