 2.3.3 Information About the History List
 ----------------------------------------
 
 These functions return information about the entire history list or
 individual list entries.
 
  -- Function: HIST_ENTRY ** history_list (void)
      Return a `NULL' terminated array of `HIST_ENTRY *' which is the
      current input history.  Element 0 of this list is the beginning of
      time.  If there is no history, return `NULL'.
 
  -- Function: int where_history (void)
      Returns the offset of the current history element.
 
  -- Function: HIST_ENTRY * current_history (void)
      Return the history entry at the current position, as determined by
      `where_history()'.  If there is no entry there, return a `NULL'
      pointer.
 
  -- Function: HIST_ENTRY * history_get (int offset)
      Return the history entry at position OFFSET, starting from
      `history_base' ( History Variables).  If there is no entry
      there, or if OFFSET is greater than the history length, return a
      `NULL' pointer.
 
  -- Function: time_t history_get_time (HIST_ENTRY *entry)
      Return the time stamp associated with the history entry ENTRY.
 
  -- Function: int history_total_bytes (void)
      Return the number of bytes that the primary history entries are
      using.  This function returns the sum of the lengths of all the
      lines in the history.
