+B1 and b1 have the same key, and their subjects are also equal (after
+normalization).
+
+C, C', and C'' all have the same subject but different keys (doesn't matter for
+this test).
+
+C and C' should chain up through both B1 and b1, since they have the same key
+and the names are equal after normalization.
