Okay, then. 
Particular since:
  * the difference between the old behavior and the pretest behavior is
    that one bug was fixed, making it easier to see another bug which
    had been around a while (the pretest buggy behavior wasn't new),
  * the changes since the pretest have been simple, but not trivial,
I'll leave the pretest alone.
