+ and all word separators,
+ plus any adjacent letter-spacing or word-spacing
+ when located then end of the line.
+
+
- 2. Rescued L3 Brainstorming: Ignore For Now
+ Should object trailing-spaces be the initial value instead of just object?
+ Should the initial value be auto,
+ defined so that that it can vary between
+ object and object trailing-spaces
+ depending on properties like white-space, word-wrap, word-break etc?
- 2.1.
+ Should we have a leading-spaces value as well?
+ It looks like object leading-spaces may be more appropriate than
+ object trailing-spaces in right-aligned text,
+ even though common word processing applications don’t do that.
