agenda+ FOR REVIEW: Managing inline spaces in Chinese & Japanese

Managing inline spaces in Chinese & Japanese
https://w3c.github.io/i18n-drafts/articles/styling/inline-space.en


This is a first review.  Note that:

1. the greyed out text at the bottom will be removed
2. i need some better Chinese text examples

This is still an early draft, and i'm looking for a sense check at this 
point.


thanks,
ri
