Summary: Inconsistency between StringIO and cStringIO
Initial Comment:
The readline method for StringIO defalt argument for
the size arguement is None while for all other
file-like objects it is -1. So if we pass in -1 to the
StringIO readline method, all lines are returned, again
inconsistent with the other file-like objects, and if
we pass in None to any other file-like object we get a
TypeError, int required.
The attached python script is a very simple example of
what I mean.
Note that this is causing me a lot of grief in trying
to get tests to pass for a simple fix to an open source
project.

BTW, another inconsistency between StringIO and cStringIO :-)
>>> import cStringIO as c
>>> sio = c.StringIO()
>>> sio.write("aaaaa")
>>> sio.truncate(0)
>>> print sio.getvalue()
>>> sio.write("bbbbb")
>>> print sio.getvalue()
aaaaabbbbb
which I get in StringIO module is "bbbbb".
