-- 1. revisions that should stand for a page creation without a corresponding record in the page table
-- REASON: move_redir orphans records in the revision table instead of archiving them like the move_and_delete
--   MovePage::moveToInternal $moveOverRedirect, $newpage->doDeleteUpdates 503
--   as opposed to the correct: SpeicalMovepage.php $page->doDeleteArticleReal line 559
