 2.2 History Storage
 ===================
 
 The history list is an array of history entries.  A history entry is
 declared as follows:
 
      typedef void *histdata_t;
 
      typedef struct _hist_entry {
        char *line;
        char *timestamp;
        histdata_t data;
      } HIST_ENTRY;
 
    The history list itself might therefore be declared as
 
      HIST_ENTRY **the_history_list;
 
    The state of the History library is encapsulated into a single
 structure:
 
      /*
       * A structure used to pass around the current state of the history.
       */
      typedef struct _hist_state {
        HIST_ENTRY **entries; /* Pointer to the entries themselves. */
        int offset;           /* The location pointer within this array. */
        int length;           /* Number of elements within this array. */
        int size;             /* Number of slots allocated to this array. */
        int flags;
      } HISTORY_STATE;
 
    If the flags member includes `HS_STIFLED', the history has been
 stifled.
