Patch including backwards compatibility

Agreed.  I've attached a patch which is more strict.  It's true that it's a
little more complex, but I also think it's more self contained, documented and
easier to remove in the future.

If this is preferred I'd recommend reverting d3bd3ec and applying this one
instead.

I've also created a patch which could be applied to the 1.2 stable branch if
acceptable.  It's just the same but there is no deprecation warning as it
doesn't make sense to include that in a stable release.
