        * io.c (error_element), (format_locus):  New static globals.
        (unexpected_element):  Spelled out this message fully.
        (next_char):  Keep track of locus when not MODE_STRING.
        (next_char_not_space):  Remember last parsed element in error_element.
        (format_lex):  Fix two indentation errors.
        (check_format):  Use format_locus and possibly error_element for a
        slightly better error message on invalid format.
        (check_format_string):  Set format_locus to start of the string
        expression used as format.

        * io/format.c (struct format_data):  New member error_element.
        (unexpected_element):  Added '%c' to message.
        (next_char):  Keep track of last parsed character in
fmt->error_element.
        (format_error):  If the message is unexpected_element, output the
        offending character, too.
