Single expressions function declaration use of Join Lines wrong without braces

eg:

function foo (v) {
  return v * 2
}

Now select the function and press Ctrl+Shift+J or Ctrl+Shift+A to execute Join Lines

The code will change to:

function foo (v) return v * 2

However, JavaScript doesn't seem to allow such statements, and I've been told syntax errors in Node or in the browser.

Expected:

function foo (v) { return v * 2 }
