  | Has anyone scanned NetBSD's (or pkgsrc's) codebase for such uses?

I am in the process of doing that - that's what led to PR lib/52779
we have code that does

	dir = dirname(buf);
	strlcpy(buf, dir);

which I suspect is probably an undefined sequence, that happens to work.

  | What does Windo^WLinu^Wglibc do?

Not sure, but the austin group people wouldn't be suggesting changing
things in a way that would be fatal to them I think/

  | Is this becasuse the basename of "C:\Program Files\Important\" is defined 
  | to be "Important" sans slash -- err, of "/etc/pam.d/" to be "pam.d"?

Yes.
