Code review comment for lp:~townsend/libertine/refactor-lcm

Thanks!

As discussed on IRC, double space vs. single space is a pyflakes thing of functions outside a class vs. inside a class.

I did not merge _test_key_value_exists() and _test_array_object_key_value_exists() as you suggested because I think doing so may introduce more complexity in what I'm trying to do there:)
