You are right here. The fix for find is to specify '+' to prevent this
behaviour. For su, it depended on an undocumented feature of getopt(3)
and should be fixed now. I'll go through the other users of getopt(3)
today, but I don't expect major trouble for anything outside, since this
is the default behaviour of GNU's getopt.
