[issue18524] BufferedReader.read1() documentation/implementation difference

[R. David Murray]

R. David Murray added the comment:

Unless I'm misunderstanding something, the current implementation does match the current documentation: if <buffer-size> < n, returning <buffer-size> bytes is returning "up to n".  "Up to" means it could be "less than".

So you are advocating a change in behavior...but I believe there is a reason read1 is implemented the way it is, so I suspect that isn't going to happen.  Probably what you want to do is change the buffer size when you open the file so that it is greater than your 'n'.
