[PATCH] obstack_printf fix (fixes localedef)

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

We cannot call obstack_blank, because we call then
  _IO_str_init_static (&new_f.ofile.file.file, obstack_base (obstack),
                       size, obstack_next_free (obstack));
			     ^^^^^^^^^^^^^^^^^^^^^^^^^^^
and obstack_next_free points to wrong place in that case (64bytes away from
where it should).
With this patch, obstack_printf seems to work just fine to me even in the
case where it is called with
obstack_object_size (obstack) == obstack_room (obstack) == 0.

	* libio/obprintf.c (_IO_obstack_vprintf): Call obstack_make_room,
	not obstack_blank.
