No, it's not that simple, because there might be other keys that are
TRUE not MAYBE. So the result could legitimately be TRUE in this case.
BTW, I think it'd be a really good idea for this function to restore
all the MAYBE entries to GIN_MAYBE before returning, so that you can
remove the caveat that it destroys the contents of entryRes[]. I have
basically zero faith that that's safe, and it seems pretty cheap to
not have to make the assumption.
