[issue23214] BufferedReader.read1(size) signature incompatible with BufferedIOBase.read1(size=-1)

[Martin Panter]

Martin Panter added the comment:

Okay here is a patch implementing read1(-1) in BufferedReader and BytesIO (my original proposal). Other changes:

* Changed read1(size=-1) → read1([size]), because BufferedReader and BytesIO do not accept keyword arguments (see also Issue 23738)
* Defined size=-1 to mean an arbitrary non-zero size
* Change BufferedReader.read1() to return a buffer of data
* Change BytesIO.read1() to read until EOF
* Add tests to complement existing read1(size) tests for BufferedReader (includes BufferedRandom), BufferedRWPair, and BytesIO
