Issue481404

When reading a file opened with the 'b' flag on unix 
cause any CR character to be removed from data.

This does not match the behaviour of CPython.

>>> f = open("foo", "w")
>>> f.write("abc\r\n")
>>> f.close()
>>> f = open("foo")
>>> f.readline()
'abc\n'
>>>

Logged In: YES 
user_id=145274

It happens on both Unix and Windows, but only with text read.

>>> f = open('foo', 'w')
>>> f.write('abc\r\n')
>>> f.close()

C:\>od -x foo
0000000000      6261    0D63    0A0D
0000000006
C:\>python -c "print open('foo', 'rb').readlines()"
['abc\r\r\n']
C:\>\jython-2.1\jython -c "print open('foo', 'rb').readlines()"
['abc\r\r\n']
C:\>python -c "print open('foo').readlines()"
['abc\r\n']
C:\>\jython-2.1\jython -c "print open('foo').readlines()"
['abc\n', '\n']

$ od -x foo
0000000 6261 0d63 000a
0000005
$ python2 -c "print open('foo', 'rb').readlines()"
['abc\r\n']
$ jython -c "print open('foo', 'rb').readlines()"
['abc\r\n']
$ python2 -c "print open('foo').readlines()"
['abc\r\n']
$ jython -c "print open('foo').readlines()"
['abc\n']

This appears to be fixed with the PyFile cleanup.
