I believe I have taken care of this problem as part of the optimizer
overhaul I am doing for 6.6.  I was not planning to back-patch any of
this work for 6.5.2, however --- too many changes, not yet enough
testing.  If you pull down a current snapshot you should be able to
see what I have done with add_pathlist.
