[issue20578] BufferedIOBase.readinto1 is missing

[Nikolaus Rath]

Nikolaus Rath added the comment:

I have attached a patch that adds readinto1() to BufferedReader and BufferedRWPair.

An example use case for this method is receiving a large stream over a protocol like HTTP. You want to use a buffered reader so you can efficiently parse the header, but after that you want to stream the data as it comes in, i.e. you want to use read1 or, for improved performance, readinto1.

Feedback is welcome.
