Archaic Pashto letter

Arabic letter U+0682 shows two dots above.
It has the cryptic remark "not used in modern Pashto".
But was it ever used?

The new 2011 edition of German standard DIN 31635
"Romanization of the Arabic Alphabet"
 http://www.beuth.de/en/standard/din-31635/140593750
shows the real archaic Pashto letter on page 22.

It has one dot above and one dot below,
corresponding to Pashto U+0696 and U+069A.

This is also the form shown in "Lehrbuch des Pashto
(Afghanisch)" von Manfred Lorenz.

/* The current form for [dz] is U+0681. */
