Original change's description:
> Support key up/down to move through query history.
> 
> We follow the behavior of linux shell:
> (1) Whenever there is a new query, the iterator is reset to the new
>     query.
> (2) Prev of the iterator moves till the first query and stick there.
> (3) Next of the iterator can move beyond last query and get an empty
>     query.
