I wrote 'current convention' not just as a statistical statement, but 
as a prescription I had read, even though I did not remember just where. 
PEP8 says
   "PEP 257 describes good docstring conventions."
I followed that clue found the statement I had read.  PEP 257 says
'''
It [the one line docstring] prescribes the function or method's effect 
as a command ("Do this", "Return that"), not as a description; e.g. 
don't write "Returns the pathname ...".
'''
Whether the reference in PEP 8 makes it a PEP 8 rule? or a 'strict 
stdlib position'?

http://bugs.python.org/issue19067 proposes to change rangeobject 
docstrings. Is that OK or should the issue be rejected and closed?
