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)
Using "ambig_set" as an array. This might corrupt or misinterpret adjacent
memory locations.
272 ambig_set[option_index] = 1;
I guess we can ignore it?
Yes, let's do that. We're already ignoring what must be hundreds of
Coverity false positives, and there's little harm in ignoring one more.
