- * That means that once we get to REV_TREE_DIFFERENT, we do not
- * have to look any further.

+ * The only time we care about the distinction is when
+ * remove_empty_trees is in effect, in which case we care only about
+ * whether the whole change is REV_TREE_NEW, or if there's another type

+ *
+ * 2. We saw anything except REV_TREE_NEW.
