I considered doing that, but decided not to because it would be too
fragile.  The test relies on the fact that the parser does error
recovery in a very particular way, turning a (humanly-obvious)
missing-semicolon error into multiple complains about a (K&R) argument
declaration.  I figured we'd be better off no relying on that.
