Term by term difference of two lists : `-
.-`

The infixed operator `-` or `.-` and the prefixed operator
`'-'` returns the term by term difference of two lists.

If the two lists do not have the same size, the smallest list is
completed with
zeros.

Input :
`[1,2,3]-[4,3,5]`

Or :
`[1,2,3] .+ [4,3,5]`

Or :
`'-'([1,2,3],[4,3,5])`

Or :
`'-'([[1,2,3],[4,3,5]])`

Output :
`[-3,-1,-2]`

**Warning !**

When the operator `-` is prefixed, it should be quoted (`'-'`).
