Re: [iip] Dandas are wrapped alone to the beginning of a line (#105)

Dandas are already Break After (BA) in [UAX #14](https://unicode.org/reports/tr14/#BA) (see section “Dandas”), the class for general closing characters.

A long-standing issue though, is if dandas should be further specified to behave like [Exclamation/Interrogation (EX)](https://unicode.org/reports/tr14/#EX) so a preceding space (it’s a common style to surround dandas with a pair of spaces, like the French way of typesetting question and exclamation marks) doesn’t cause a linebreak either. This issue ticket may be actually referring to that situation.
