[docs] [issue9343] Document that argparse "parents" must be fully declared before children

Éric Araujo <merwok@netwok.org> added the comment: I removed 3.3, since it currently means “won’t be done for 3.2, so note for later.” I don’t know if the report applies to 3.1 (doc fixes go into stable releases too), so I’m not adding it. ---------- nosy: +merwok versions: -Python 3.3 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue9343> _______________________________________
