[issue10219] BufferedReader.read1 does not check for closed file

[Amaury Forgeot d'Arc]

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:

The following snippet should raise ValueError (twice :-)

f = open('foo', 'rb')
print(f.read1(1)) # OK
f.close()
print(f.read1(5)) # expected ValueError("I/O operation on closed file")
print(f.peek())   # expected ValueError("I/O operation on closed file")

The _pyio implementation of BufferedReader.read() has the same issue.
