* Add an index to (rev_page,rev_user,rev_timestamp) for use in "All edits by a user to this page".  Also potentially useful for "edits to a page grouped by user".  (Would "edits by a user grouped by page" be more useful instead?)  See bug 10788.  Code to implement that feature will follow at some point when the index has actually been applied to Wikimedia servers, probably shortly after I get annoyed at its nonexistence again when looking for an old edit of mine.
