This saves trouble in a number of places where we can now do joins with the link tables to get other info (such as cur_is_redirect!) as well as the name, and fewer bits need to be juggled on page renaming, as outgoing links no longer have to be changed (cur_id remains the same when a page is renamed).
rebuildLinks.inc and some of the tools in the 'maintenance page' still need to be updated to work with the new setup. (Special:Maintenance needs a *lot* of cleanup in general. It's kind of a catch-all of vaguely defined features which suck performance like a hydroelectric dam.)
Also I've slipped in some extra debug code. And, I think 'indexes.sql' is a big waste of time and should all be moved into tables.sql. Building indexes separately doesn't help on InnoDB and won't do anything on MyISAM either if you're just going to replace the table after it's built with an imported one from a dump which creates it with indexes.
changes (bug #845036). User contributions and related changes now
ignore this preference.
Also, fixed a problem where the show/hide minor edits link wasn't
appearing on recent changes and related changes. Made sure that the
param gets passed through with all the links.
Made sure that user contributions also had a show/hide minor edits
thing, and that minor edits are flagged with the M (or whatever) in
user contributions.
