Justify-to option

[Thanatermesis]

Seems like by default the justification starts counting from the left, sometimes its needed to be from the right but after to read the doc I don't see a way to do it.

For example:

arr1, arr2, arr3, arr4, arr2, arr3, arr4, arr3, arr4, arr1, arr2, arr3, arr4,

As you can see on this example it is a list of items which should be justified to the right, like this:

> arr1, arr2, arr3, arr4,
>       arr2, arr3, arr4,
>             arr3, arr4,
> arr1, arr2, arr3, arr4,

This may sound also like a feature needed to "start counting from the right" instead of from the left, not sure
