+/**
+ * Our Locations come from two places: (1) direct user input and (2) ones
+ * guessed by the system, such as from geoclue or timedate1.
+ *
+ * Since the latter only have a timezone (eg, "America/Chicago") and the
+ * former have a descriptive name provided by the end user (eg,
+ * "America/Chicago Oklahoma City"), this function tries to make a
+ * more human-readable name by using the user-provided name if the guessed
+ * timezone matches the last one the user manually clicked on.
+ * 
+ * In the example above, this allows the menuitem for the system-guessed
+ * timezone ("America/Chicago") to read "Oklahoma City" after the user clicks
+ * on the "Oklahoma City" menuitem.
