Now rebased again, so should work with latest master. "Protecting" is probably
a little bit misleading to reflect what the patch currently does, it has been
largely refactored since the first version (which I did not write). I have
renamed it to MARC merge rules instead, since it is more of a framework for
auto-merging records according to a set or rules. My experience is that is is
really tricky to get this right, and if trying to fit it into another
abstraction that might not be suited for this exact purpose it could be more
trouble than it's worth
