Why is everybody making this more complicated than it needs to be?

This not necessary, because neither was the rescan. Close Bitcoin-Qt if it's still running (and be sure to wait for it to fully shut down), delete (or rename, if you're paranoid) the empty wallet.dat created by Bitcoin-Qt when you first attempted to start it, rename wolverine.dat back to wallet.dat, and restart Bitcoin-Qt. Your balance should be displayed immediately; there is normally absolutely no need for a rescan when restoring a wallet backup.
