I believe I added it, commented out, for the time when we enabled a 2.12
build. My concern is just that it leaves the checkout in a state that builds
for 2.12. If you tried a 2.11 build afterwards it would fail. But I suppose it
would clearly fail. I suppose it will work here as it's the last thing this
tries to do, so the end state doesn't matter. Tidy, but optional to set it back.
