Bug 17483 has been resolved, but we have kept the line breaking descriptions.
However, bug 28432 should resolve this when we use CSS's new 'text-wrap:
balance' (maybe the I18N WG can make sure that this new property works for
different scripts?).

BTW: overflow hidden is being used on regions because they have a limited
number of lines and we want lines that scroll up to disappear. Since normal
cues don't have a limited number of lines, they won't need overflow hidden.

To address the remaining issues of this bug, should we put default values on
'line-break:auto' and 'word-break:normal' and should we replace
'word-wrap:break-word' with 'word-wrap:break-word'?
