sortby misdocumented

[GoogleCodeExporter]

Wiki says that sortby behaviour can be swich off by setting it to None:

The behaviour will persist until you turn it off: 
x.sortby = None

But this raises an error:

In [57]: x.sortby = None

Thanks for reporting this!  While the documentation is currently wrong, it 
describes the way that *things* should work, so I will change the code in the 
next release.

• Changed state: Accepted

This has been fixed in trunk, so the correct behaviour will be seen in 0.7, 
which I am hoping to release later today.
