[New-bugs-announce] [issue13087] C BufferedReader seek() is inconsistent with UnsupportedOperation for unseekable streams

New submission from John O'Connor <tehjcon at gmail.com>:

The C implementation of BufferedReader.seek() does not throw an UnsupportedOperation exception when its underlying stream is unseekable IF the current buffer can accommodate the seek in memory. It probably saves a few cycles for the seekable streams but, I think currently, it is inconsistent with the _pyio implementation and documentation.
