Title: Allow a single subject to be re-embedded in each top-level frame match.  (I hope this behavior is intentional.)

[Example in playground](http://tinyurl.com/c63bge8)

I *really* like this new behavior, but I didn't notice any positive test coverage, so I wanted to make sure it's real.

(Note: I'd *really, really* like a more generalized approach to re-embeds that allowed arbitrary re-embedding of a subject as long as the direct path from embed-to-root didn't include that subject. This could generate some verbose frame matches, but would still avoid circularity. My alternative is to fashion this kind of graph in-memory, using a framed result as the input...)
