Indeed, read1() is not documented as a standard method of either IOBase,
RawIOBase or BufferedIOBase. I suggest that it becomes a standard method
of IOBase, with a default implementation simply calling read(n).

It also means unbuffered stdio as it was recently committed doesn't work
for stdin:

$ ./python -u
Python 3.1a0 (py3k:68756, Jan 19 2009, 01:17:26)

>>> import sys
>>> sys.stdin.read(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/antoine/py3k/__svn__/Lib/io.py", line 1739, in read
    eof = not self._read_chunk()
  File "/home/antoine/py3k/__svn__/Lib/io.py", line 1565, in _read_chunk
    input_chunk = self.buffer.read1(self._CHUNK_SIZE)
AttributeError: 'FileIO' object has no attribute 'read1'
>>> 

I had been misguided by the fact that the interpreter prompt did work,
but it doesn't seem to use sys.stdin...
