[docs] [issue16701] Docs missing the behavior of += (in-place add) for lists.

[Ashwini Chaudhary]

New submission from Ashwini Chaudhary:

I think the python docs are missing the behavior of += for lists. It actually calls list.extend() but can't find that anywhere in docs expect in source code, http://hg.python.org/cpython/file/2d2d4807a3ed/Objects/listobject.c#l892.
