That patch looks good to me.  While we're at it, can we also add the
following related functions, which are used to control the maximum
size of the history file?  (They're also provided by editline.)

void		 clear_history(void);
void		 stifle_history(int);
int		 unstifle_history(void);
int		 history_is_stifled(void);

Thanks,
