[issue19215] StringIO.StringIO('foo').readline(0) == 'foo'

[Zdeněk Pavlas]

New submission from Zdeněk Pavlas:

The behavior contradicts documentation and is inconsistent with both cStringIO and File objects.  Patch attached.

>>> StringIO.StringIO('foo').readline(0)
'foo'
>>> cStringIO.StringIO('foo').readline(0)
''
>>> open('/etc/passwd').readline(0)
''
