I've heard of such case on a FBW Airbus - though I can't find any links, maybe it's just an urban legend. After some maintennance, the capt sidestick was incorrectly connected and gave reverse aileron signal. Fortunately the other sidestick was o.k. and they made it back. As for the old French planes - they also had reverse throttles - i.e. to get full power you needed to pull the trottles all the way back. I'm glad those mad days are long gone
