  If you take the well-known example (Wach-stube / Wachs-tube and
probably some others I can't remember), it depends on semantics anyway,
and the user may have to specify manually which s to use from time to
time. OK, admittedly this is a really special example, and most of the
time we can simply used patterns similar to hyphenation patterns.
