[clreq] How does line start/end overflow work for romanised phonetic annotations?

r12a has just created a new issue for https://github.com/w3c/clreq:

== How does line start/end overflow work for romanised phonetic 
annotations? ==
The following  is my understanding of the jLReq rules for dealing with
 situations where an annotation would otherwise protrude outside a 
line start or end.  Are the Chinese rules the same or different? (In 
either case, it would be useful to say something in cLReq, i  think.)

---

_Is the annotation longer than the base text?_
        NO      There’s no problem to solve here. Stop.
        YES     Carry on.

_Is the annotation wanting to extend beyond the line start or end?_
        NO      You need to use rules about overhang, rather than 
these. Stop.
        YES     Carry on.

_You have two choices:_
1. FLUSH        Both annotation and base are aligned with line end. 
The annotation is aligned with the start of the base (_katatsuke_).

2. OFFSET       The base is moved away from the line end. The 
annotation is aligned with the middle of the base (_nakatsuke_).

In either case, the bit of the annotation that overflows the base on 
the inside of the line will need to be positioned relative to the 
adjacent base characters using the rules for overhang (which are 
described elsewhere).

_Did you choose FLUSH when there are multiple base characters for the 
annotation (ie. group ruby)?_
        NO      You’re ok. Stop.
        YES     You should spread out the base characters, using equal
 amounts of space.
