Thanks very much! That works perfectly. By the way, you asked if I had
changed *history_meta.py* at all: I added some properties on *Versioned* to
allow conditional versioning:

The use case being that I only want to create a new version if the user
saving an object is different from the user who last saved it. I also
thought about adding an explicit *Versioned.create_version* method, but
this suffices for now.
