bug#13888: patch for python indentation

User-agent: Notmuch/0.15.2+43~ge848af8 (http://notmuchmail.org) Emacs/24.3.50.1 (x86_64-unknown-linux-gnu)

A previous version of emacs’ python-mode would unindent the line after a
pass or retrun keyword, which end the current block.  The current
version does not do so.  The attached patch restores this behavior.
