	than the read request.  Loop over subrecords.  Set an error if the
	user has set a recl and the read was short.
	(write_buf):  Separate codepaths for unformatted direct and
	unformatted sequential. If a recl has been set by the

	than the read request.  Loop over subrecords.  Set an error if the
	user has set a recl and the read was short.
	(us_read):  Add parameter continued (to indicate that bytes_left
	should not be intialized).  Change default of record marker size
	to four bytes. Use subrecord.  If the subrecord length is smaller than
	zero, this indicates a continuation.
	(us_write):  Add parameter continued (to indicate that the continued
	flag should be set).  Use subrecord.
	(pre_position):  Use 0 for continued on us_write and us_read calls.
	(skip_record):  New function.
	(next_record_r_unf):  New function.
	(next_record_r):  Use next_record_r_unf.
