Hi all,

I could finally get to checking RFC 4645bis and RFC 4646bis. I was
wondering what it would take to make "pes", and "prs" (defined in ISO
639-3 to be for "Western Farsi" and "Eastern Farsi/Dari") to become
extended languages subtags of "fa" (Persian).

This is of course for historical reasons too, since Dari has been tagged
using "fa" or "fa-AF" all these years. (In CLDR and Computer Locale
Requirements for Afghanistan [http://www.evertype.com/standards/af/]).
