   When there are two choices (i.e. boolean), return 1 if the value is
   different from normal value and 2 if the value is the same as the
   normal value.  E.g. "%?Sp<%Sp>" would show the pitch only when
   playing at a modified pitch.

   When there are more than two choices (i.e. enum), the left half of
   the choices are to show 0..normal range, and the right half of the
   choices are to show values over that.  The last entry is used when
   it is set to the normal setting, following the rockbox convention
   to use the last entry for special values.

   E.g.

   2 items: %?Sp<0..99 or 101..infinity|100>
   3 items: %?Sp<0..99|101..infinity|100>
   4 items: %?Sp<0..49|50..99|101..infinity|100>
