And I'll stress that my change doesn't change traversal behavior
either for any case that didn't emit and Unauthorized error
previously. It is also completely compatible with Dieter's proposal,
which is worthwhile because it could allow many existing
__bobo_traverse__ methods to be greatly simplified. I've applied my
patch to 2.8, 2.9, and trunk because a Zope release appears to be
imminent, and there's no way we can release a new Plone until we have
a Zope/Five which can handle acquisition properly (I'm pretty sure
that this will bite other projects as well).
