About that: is read1() argument mandatory or not?

In _pyio, BufferedIOBase.read1() argument is optional (default: None); BytesIO.read1(), BufferedReader.read1(), BufferedRWPair.read1(), BufferedRandom.read1() argument is mandatory.

In _io, BufferedIOBase.read1() raises directly an exception, without checking the arguments; BufferedReader.read1() argument is mandatory.

In the io doc, BufferedIOBase.read1() argument is optional (default: -1), BytesIO.read1() has no argument (!) and BufferedReader.read1() argument is mandatory.
