Doc: add comment about bug fixed in back branches as of 3f7323cbb.

While the bug I just fixed in the back branches doesn't exist in
HEAD, the requirement that MULTIEXPR SubPlans not share output
parameters still does.  Add a comment to memorialize that, because
perhaps it could be an issue again someday.
