Actually, this semantic seems to be going away soon, but until it does...

difference between "inactive" and "in!active" (where "!" represents ZWNBSP),
namely that at the end of a line such as this one, it is correct to show "in-
active" with hyphenation, whereas "in!active" at the end of a line must be
"inactive", with wordwrap.
