[Python-3000] PEP 3131 - the details

That is my reasoning, too. People seem to want to be conservative,
so it's safer to reject formatting characters for the moment.
If people come up with a need, they still can be added.

(there might be a need for it in RTL languages, supporting
200E..200F and 202A..202E, but it seems that speakers of RTL
languages are skeptical about the entire PEP, so it's unclear
whether allowing these would help anything)
