[docs] [issue19560] PEP 8 operator precedence across parens

[Tom Lynn]

New submission from Tom Lynn:

PEP 8 currently has::

  Yes::

      ...
      c = (a+b) * (a-b)

  No::

      ...
      c = (a + b) * (a - b)

That looks wrong to me -- surely the parens are a sufficient
precedence hint, and don't need further squashing inside?
This will be worse with any non-trivial example.  I suspect
it may also lead to silly complications in code formatting tools.

This was changed by Guido as part of a reversion in issue 16239,
but I wonder whether that example was intended to be included?
