Bug 247438

// input.js
print (
    String(function f () {})
);
__________________________

Hello,

The space between `f` and `()` should be retained in the result of toString of the generator function, but JSC removes all the space between them.

Running the input.js with JSC prints

---
$ jsc input.js
f() {}
---

while other engines behave like

---
# V8 (used console.log)
$ node input.js
f () {}

# GraalJS
$ js input.js
f () {}
---
