can distinguish the erasure of the element associated with key=@
`unset -v a[$key]' from the entire array erasure `unset -v a[@]'.
As a counter-proposal, Chet could entirely remove the special meaning
of unset 'a[@]' and introduce a new option to unset which would take
its place. It appears -a is not yet used, so that would be a good pick.
No need, since a bare `unset a' already removes the array variable a.
