Redirect alternative paths to the honeypot script

I've noticed that some bot(s) regularly visit not only thesubdir/thescript.php, but also a bunch of other/thesubdir/thescript.php paths, where "other" is an existing path component, but other/thesubdir/thescript.php gives 404.

I think it would make sense to redirect all */thesubdir/thescript.php requests to thesubdir/thescript.php. And it would give some relief to watchdog, too.
