We re-worded the “otherwise forbid” to make it clear.

Now the spec allows breaks between “$” and “100” for “$100” when the line-break property is “loose", and that behavior was raised as possible issue for implementers, and that not allowing the breaks is fine for Japanese, I changed the definition of the “loose”[1].

Please let me know if any.
