Opt Subject: PRI #357: Incomplete definition of Extender

UAX #44 defines Extender as “Characters whose principal function is to extend the 
value or shape of a preceding alphabetic character. Typical of these are length 
and iteration marks.” It is also used for characters whose function is to extend 
the shape of an adjacent (not necessarily preceding) character, such as U+0640 
ARABIC TATWEEL.
