[Zope-dev] CopySupport bug or feature?

I've been able to get around this by creating a _notifyOfCopyTo on the
folder type that does the recursion.  There's a delicate dance in some
of my code that does some work in _notifyOfCopyTo and other work in
_getCopy.  This could be improved I bet, but touching the code means
that you surely own it forever. ;-)
