# HG changeset patch
# User Bram Moolenaar <bram@zimbu.org>
# Date 1273862465 -7200
# Node ID 99b225e0dbc1989ecae75200aaf0e5329e6bedac
# Parent  2bd29808d1f640f027ab7a4a4f2b5b6a0e6c8e38
updated for version 7.2.430
Problem:    The ++bad argument is handled wrong, resulting in an invalid
	    memory access.
Solution:   Use the bad_char field only for the replacement character, add
	    bad_char_idx to store the position. (Dominique Pelle)
