Follow-up Comment #6, patch #9757 (project avrdude): Hi Jörg,
it took me some time to verify this because between me proposing this patch and your comment, a regression has been introduced: The last revision that my patch works on is r1435. r1436 breaks this programmer again—even with my patch applied. See the extra verbose output for r1436 with my originally suggested patch attached at the end of this post. On r1435, I tried your patch. It works just as well as my proposed patch. I agree that your patch is cleaner if it's safe to assume that programmers have only up to one ID.
