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.
