Finish incomplete revert of ec63622c0.

The code change this made might well be fine to keep, but the
comment justifying it by reference to self-join removal isn't.
Let's just go back to the status quo ante, pending a more thorough
review/redesign of SJE.

(I found this by grepping to see if any references to self-join
removal remained in the tree.)
