[Omit needless words] Move a paired preposition into the first argument label.

If the second argument label starts with a preposition for a split
selector, move the preposition into the first argument label. For
example:

-  func transitionFrom(fromViewController: NSViewController, to
toViewController: NSViewController, options:
NSViewControllerTransitionOptions = [], completionHandler completion:
(() -> Void)? = nil)
+  func transition(from fromViewController: NSViewController, to
toViewController: NSViewController, options:
NSViewControllerTransitionOptions = [], completionHandler completion:
(() -> Void)? = nil)
