[New-bugs-announce] [issue5265] StringIO can duplicate newlines in universal newlines mode

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

This one is a bit strange:

>>> f = io.StringIO("a\r\nb\r\n", newline=None)
>>> f.read()
'a\nb\n'
>>> f = io.StringIO("a\r\nb\r\n", newline=None)
>>> f.read(6)
'a\nb\n'
>>> f = io.StringIO("a\r\nb\r\n", newline=None)
>>> f.read(5)
'a\n\nb\n'
