 681         variable length.
 682         * io/open.c (new_unit): Don't set delim status to none if not
 683         specified so that DELIM_UNSPECIFIED can be used later.
 684         * io/transfer.c (data_transfer_init): For namelist I/O, if the
 685         unit delim status is unspecified set the current status to quote.
 686         Otherwise, set current status to the unit status.
 687         * io/unit.c (get_internel_unit, init_unit): Remember to set
 688         flags_delim initially to DELIM_UNSPECIFIED so defaults come out
 689         correctly.
 690         * io/write.c (write_character): Add a new function argument
 691         "mode" to signify that raw output is to be used vs output with
 692         delimiters. If the mode is set to DELIM (1) proceed with
 693         delimiters. (list_formatted_write_scalar): Write the separator
 694         only if a delimiter was previously specified. Update the call to
 695         write_character with the mode argument given.
 696         (namelist_write_newline): Use the mode argument. (nml_write_obj):
 697         Use the mode argument. Remove use of tmp_delim. Write the
 698         semi-colon or comma correctly only when needed with using
 699         delimiters. Cleanup whitespace.
 700         (namelist_write): If delim is not specified in namelist I/O,
 701         default to using quotes. Get rid of the tmp_delim variable and
 702         use the new mode argument in write_character.
