On Special:Undelete, the [un]deletion log is shown separately from page history. While that's useful for quickly identifying who deleted or restored a page and when, it often makes it very difficult to get an accurate picture of a complicated page history. It would be extremely useful to provide an option to show [un]deletion events in their actual historical context, i.e. mixed in with the page history.
T14083: Special:Log should be able to list pages at revision level as well
