Update.
	* iconv/gconv_simple.c (internal_ucs4le_loop_unaligned): Return
	__GCONV_EMPTY_INPUT only if input is really empty.  Otherwise
	__GCONV_INCOMPLETE_INPUT.
	(ucs4le_internal_loop): Likewise.
	(ucs4le_internal_loop_unaligned): Likewise.
	* iconvdata/unicode.c (PREPARE_LOOP): Likewise.
	* iconvdata/utf-16.c (PREPARE_LOOP): Likewise.
	* iconvdata/utf-32.c (PREPARE_LOOP): Likewise.

	* iconv/loop.c (LOOPFCT): First test for empty input then for full
	output buffer.
