Vas Crabb 97b6717027 (nw) Clean up the mess on master
This effectively reverts b380514764 and
c24473ddff, restoring the state at
598cd52272.

Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline.  When things like this happen, it wastes
everyone's time.  I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.
