	* iconv/gconv_db.c (increment_counter): Reset __init_fct, __fct,
	and __end_fct fields of struct __gconv_step.
	* iconv/Makefile (tests): Add iconv-bug2.
	* iconv/iconv-bug2.c: New file.

	* iconvdata/euc-kr.c (BODY for FROM_LOOP): Pass 'inend - inptr'
	instead of 'inptr - inend' to ksc5601_to_ucs4.

	* iconvdata/sjis.c (BODY for FROM_LOOP): Allow 0x7f character.

	* iconvdata/iso-2022-cn.c (BODY for FROM_LOOP): If an incomplete
	character or shift sequence is found at the end of the input
	string, return__GCONV_INCOMPLETE_INPUT instead of
	__GCONV_EMPTY_INPUT.
	* iconvdata/iso-2022-jp.c (BODY for FROM_LOOP): Likewise.
	* iconvdata/iso-2022-kr.c (BODY for FROM_LOOP): Likewise.

	* iconvdata/iso-2022-jp.c (BODY for FROM_LOOP): Return
	__GCONV_ILLEGAL_INPUT for 8bit characters.
