[issue5811] io.BufferedReader.peek(): Documentation differs from Implementation

[Lucas Prado Melo]

Lucas Prado Melo <lukepadawan at gmail.com> added the comment:

Here is a patch that passes all the tests (I had to change some of them
though, they were expecting erroneous behaviours IMHO).
The biggest problem was the read1 testing, I've tried to get the maximum
of bytes less than or equal to what the user wanted while executing at
most 1 raw_read()'s.

I have created a new test for peek()'ing a number of bytes bigger than
could possibly be stored on the buffer.
