	* unif.c (scm_uniform_array_read_x), ports.c (scm_getc): increment
	read_pos after scm_fill_buffer.
	* ioext.c (scm_do_read_line): simplify by ignoring the fill_buffer
	return char.
	* vports.c (sf_fill_buffer), strports.c (stfill_buffer),
	fports.c (fport_fill_buffer): implement the interface change.
	* ports.c (scm_fill_buffer): interface change: no longer increments
	read_pos past the character that's returned.  it seems clearer to
	leave it to the caller to decide what to do (thanks Jim).
	* vports.c (sf_fill_buffer): put the read char into the buffer
	as well as returning it.
	* ports.c (scm_grow_port_cbuf): residue of this deleted procedure
	deleted.
