Summary: When a seed sequence would lead to having no non-zero significant bits in the initial state of a `mersenne_twister_engine`, the fallback is to flip the most significant bit of the first value that appears in the textual representation of the initial state. rand.eng.mers describes this as setting the value to be 2 to the power of one less than w; the previous value encoded in the implementation, namely one less than "2 to the power of w", is replaced by the correct value in this patch.
