Glitter passes all of the tests but nested optionals 1; i've examined the 
test and my code, and I'm convinced the test is correct: my code is (too) 
aggressively subtituting the value of single-valued bindings into other 
parts of the query, which breaks in this sort of nested optional 
construct.

I'll fix that code, and I support approving these 12 tests on Tuesday.
