Implement paredit drag up/down

[bdevel]

@PEZ Thanks for the paredit push left/right.

I also recommend adding drag-down which will move an item that has a list to the left, into the list as the first item. You could then push-right to desired position.

• drag-down: (let *x* [a 1]) to (let [*x* a 1])

The drag-up would move an item out of a list and placed to the right of it.

• drag-up: (let [a 1 *x*]) to (let *x* [a 1]).

With those two added, anything can be created with structural edits. The only other drag I can think is drag-next and drag-prev which is indifferent to boundaries.

• drag-prev: (let [a 1 ] *x*) to (let [a 1 *x* ])
• drag-next: (let [a 1 *x* ] ) to (let [a 1 ] *x* )

BTW, this are comparable to clojure.zip zipper up/down, left/right, next/previous.

Thanks for these suggestions. I'll implement them all. 😄

About drag-prev/next. They look a bit like the movement commands Forward Down/Up , so I think I'll name it something like that.
