Section: 27.4.4.3 [lib.iostate.flags]

Paragraph 4 says:
> void clear(iostate state = goodbit);
>
> Postcondition: If rdbuf()!=0 then state == rdstate(); otherwise
> rdstate()==state|ios_base::badbit.

The postcondition "rdstate()==state|ios_base::badbit" is parsed as
"(rdstate()==state)|ios_base::badbit", which is probably what the
committee meant.

Proposed resolution: "rdstate()==state|ios_base::badbit" should be
replaced with "rdstate()==(state|ios_base::badbit)".
