Description

I have a foreing.js with the code:

exports.fn = (
  x, y
) => {

};

and the compiler while bundling turns it into doesn't respect existing formatting of brackets and arrows:

(function(exports) {
  exports.fn = (
    x, y)
    => {

  };
})(PS["BadForeign"] = PS["BadForeign"] || {});

putting ) not in the same line as the =>.

While this code is totally legal JS this just cased the problem for me while building with ncc: vercel/ncc#721

To Reproduce

Create a module with a foreign code above and bundle. (purs bundle ./output/BadForeign/*.js -o bad-bundle.js)

Expected behavior

Respect (at least not break in this strange way) the existing formatting of the foreign module code?
