After few days later, I re-run "make test", it's fine now.

6 unexpected results:
   FAILED  ob-D/inhomogeneous_table
   FAILED  ob-D/list-list-var
   FAILED  ob-D/list-var
   FAILED  ob-D/vector-var
   FAILED  test-org-clock/clocktable/lang
   FAILED  test-org-colview/columns-width

Because few days passed, make sure the patch is the latest version. I
attached my patch again.
