Issue Description:

With this code:

NSLayoutConstraint.activate([
    view.centerYAnchor.constraint(equalTo: self.bottomAnchor, constant: 1),
    view.centerXAnchor.constraint(equalTo: self.centerXAnchor),
])

You get:

NSLayoutConstraint.activate(
  [
    view.centerYAnchor.constraint(equalTo: self.bottomAnchor, constant: 1),
    view.centerXAnchor.constraint(equalTo: self.centerXAnchor),
  ])

I would have expected it to leave it the way it was originally

We have logic that lets opening delimiters (brace, bracket, paren) to stay on the same line as what precedes it in a function call to prevent an unnecessary level of nesting, but that was only applied to situations where the delimiter follows a colon (i.e., labeled arguments). It needs to be extended to support unlabeled arguments as well.

This was fixed for the case called out here (unlabeled single arguments) in #20. I'm holding off on declaring it done until we do the same for a labeled single argument.

#22 fixes this for a single labeled argument, so now we can close this out.
