Well, cp(1) may be the only utility affected by this change right now,
but the result has been a serious amount of confusion and
incompatibility with other POSIX compilant system in the behaviour of a
number of other commands, such as the ls(1) example I posted earlier.

Perhaps the other OSs are non-compliant in those respects, but in any
case there are now differences and something that's not particularly
required by 1003.2 (it says you use open(2) as per 1003.1, and I'm not
sure what the latter says about trailing slashes, if anything) is now
enforced to the detriment of intuitive behaviour.

NetBSD does match SCO UNIX 3.2's behaviour now though:  ;-)
