Add rule to separate case from return statement

Are you using a configuration that disables respectsExistingLineBreaks, or does this occur even when respectsExistingLineBreaks is enabled?

Using a configuration disabling existing line breaks

[allevato]

Then yes, this is working as intended; the single statement in the case fits on the same line and no line break is forced there so it makes the opinionated choice.

If this is desired behavior, we'd have to add a new configuration option to require a line break after a case.

I don't think I'd want to specialize case statements though; if we do this we should probably treat all single-statement control flow statements equally, e.g.:

// Today, if it fits
if x { foo() }

// With some new option
if x {
  foo()
}

I’ve been evaluating swift-format the last few days and the eagerness to fit as much as possible on single lines is a bit hard to swallow, while the option to respect existing breaks is too respectful. :)

This PR seemed promising until I saw the date. Is there any current work being done in this area?
