Actually, Georges Gonthier did give a formal (computer-verified) proof of the four-color theorem. Also, I believe that before that, every 5 years, someone would give a simpler version of the original proof and discover that the previous version was incomplete.

Do you have a reference for the 'discover that the previous version was incomplete' part?
