Translations:Manual:PopulateParentId.php/4/en

The first versions of populateParentId.php sorted the rev_parent_id linked list (at least with regard to those rows that had a null rev_parent_id) strictly by $revid. It assumed that the previous revision of the title was the original previous revision of the title when the edit was made. This behavior [$github was changed] by Aaron Schulz because it could result in loops.
