Actually my misuse of ifNotNilDo: in Chronology is not in the Squeak
image, it's in some *Chronology overrides in my TZ-Olson package which
is maintained externally. So it's an example of an external package
that might not be properly maintained by its deadbeat owner ;-)

So I'll fix the issues in TZ-Olson, and in any case +1 for moving
your deprecation fixes into trunk.
