partial-sort-basic-7.patch (application/octet-stream) patch

Hi!

Tom committed upper planner pathification patch.
Partial sort patch rebased to master is attached.  It was quite huge rebase
in planner part of the patch.  But I think now patch becomes better, much
more logical.
It's probably, something was missed after rebase.  I'm going to examine
this path more carefully next week.
