+/* A helper to determine the enum value for pitch/speed.
+
+   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>
+   5 items: %?Sp<0..49|50..99|101..149|150..infinity|100>
+   6 items: %?Sp<0..33|34..66|67..99|101..133|134..infinity|100>
+   7 items: %?Sp<0..33|34..66|67..99|101..133|134..167|167..infinity|100>
