The array intersection code would give wrong results if the first entry of the correct output array would be "1". (I think only this value could be at risk, since the previous word would always be a lower-bound entry with that fixed value.) Problem spotted by Julien Rouhaud, initial patch by Guillaume Lelarge, cosmetic improvements by me.
