* lisp/progmodes/python.el (python-indent-calculate-indentation): When

determining indentation, don't treat "return", "pass", etc., as
operators when they are just string constituents. 

* automated/python-test.el (python-indent-block-enders-1): Rename
from python-indent-block-enders.
(python-indent-block-enders-2): New test.
