Since there is now a log_page field that doesn't change when pages are moved or deleted, or deleted pages are recreated, we should have rebuildrecentchanges.php use the log_page field instead of the page_id as the rc_cur_id for the recent changes entries corresponding to log entries. Doing so would ensure that the page moves appear correctly when viewing the RecentChangesLinked special page for a category, and in case of deleted pages being recreated, the deletion does not incorrectly appear.
