Let's count this as +1.

Like Stefan suggests, if the opened paren is immediately followed by a
newline, the arguments will be indented less (but still indented by
additional two columns, compared to the beginning of the statement).

If that's true, could you point to:

* Some other open source project or two using this style.

* Some tutorial or step-by-step instruction for me to test this
  indentation in Vim. Do I need to install anything apart from the base
  distribution?
  Suppose I have the snippet of code typed out. What do I press next?

I don't think it's sufficient, by itself.

Take this example:

current_user.statuses.find(params[:id]).update({
  user: current_user,
  text: params[:status]
})

Suppose `update' accepted a second argument, and we wanted to pass it
here, on the next line after the hash. Which column would it be indented
to? 0?
