I have no objection to doing that --- anyone care to contribute code to
make it happen?  (I think the trick would be to fold plain-JOIN jointree
entries into FROM-list items in planner.c, somewhere near the code that
hoists sub-SELECTs into the main join tree.  But I haven't tried it, and
have no time to in the near future.)
