Message 207389 - Python tracker

I'll switch it to a deprecation warning instead sometime this week.

The changes to datamodel.rst and tarfile.py should stay, I think.

test_format and test_unicode will both verify current* behavior and check for the deprecation warning, and unicodeobject.c will generate the warning but keep current behavior.

Once 3.5 is tagged I'll put the updates to these three files there.


* By 'current' I mean accepting non-ints.
