This appears to trade a false alarm for another false alarm. Namely,
now Coverity reports:

270                           }
271                         if (ambig_set)
>>> CID 1574557:  Memory - corruptions  (ARRAY_VS_SINGLETON)

272                           ambig_set[option_index] = 1;

I guess we can ignore it?
