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

[Lucas Prado Melo]

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

We could fill the buffer while moving its start point to 0. I guess this
behavior would require a new function (or a new parameter to
Modules/_io/bufferedio.c:_bufferedreader_fill_buffer() ).
If you are ok with that I could write a patch.
