bpo-32523: Simplifying news entries with multiple paragraphs. (GH-8154)
Having multiple paragraphs in a few news entry lead to inconsistent

"sparse lists" (when at least one do).

``-r file`` runs ``file``. Python sets ``__file__`` to the startup file
name before running the file and unsets it before the first prompt. IDLE
now does the same when run normally, without the ``-n`` option.
