This issue handles the below : 

1. Adding a link to sorting HOWTO from list.sort docs as per msg327901
2. Adding multisort recipe to sorting HOWTO with an example as per msg327925.

I have raised a PR (GH-9931) for #1 but the issue35010 was closed and hence I will link to this issue. I would also suggest adding single pass sorting example

multisort recipe : https://mail.python.org/pipermail/python-ideas/2016-October/043045.html
single pass recipe : https://mail.python.org/pipermail/python-ideas/2016-October/043126.html

Since English is not my first language feedback welcome on the wording.

Thanks
