When I edit a course page and change the "Page title", I get returned to the old title, which now shows "deleted revisions". Previous edits to the course page still show up in recent changes under the old title, which is a now a red link.

I can attempt to undelete the "deleted revisions" at the old page title, but it remains empty. However a log entry for undeleting the page appears in recent changes, even though it is still a red link.

I'm not sure what the behavior ought to be, but perhaps it shouldn't be possible to move the page simply by changing the Page title in the edit interface. (Instead, moving should only be done with a standard "Move page" operation that limits the move to valid course page titles.) Alternatively, pages moved through changes in the "Page title" should leave log messages about the move (noting the old and new titles), and after the edit the user should be sent to the new title rather than the (now non-existent) old one.
