Normally, when a page is deleted, all of its corresponding recentchanges entries are deleted. But this seems to not be the case when a page is deleted to make way for a move, whether the deletion is a normal "deleted page Target" entry or a special "deleted redirect Target by overwriting" entry for a move over redirect, as the "related changes" pages for [[https://en.wikipedia.org/wiki/Special:RecentChangesLinked/Category:Candidates_for_history_merging|Category:Candidates for history merging]] and [[https://en.wikipedia.org/wiki/Special:RecentChangesLinked/Category:Candidates_for_uncontroversial_speedy_deletion|Category:Candidates for uncontroversial speedy deletion]] on Wikipedia shows. The same examples also show that pages deleted to make way for moves are not correctly removed from their corresponding categories. We need to make the "LinksDeletionUpdate" class work correctly when an existing page is deleted to make way for a move.
