Transform single line into indented block

[mgraham]

I would love to see a feature that would transform this:

    @foo = SomeClass.new(bar: 3, baz: 4, quux: 5)

Into this:

    @foo = SomeClass.new(
        bar: 3, 
        baz: 4, 
        quux: 5,
    )

So would I ;)

Taking it a step further, I'd like to line up on the colon, so you end up with both keys and values lined up. Extend this to any method() as it's defined, and last do it based on a settable word wrap length.

It's been on the list for a bit, but it's not easy and I haven't gotten it out of my head just yet.

Going either further, it should include hash objects and arrays over X length as well.
