Does automatic semi-colon insertion in JS affect for loops with the first { on a new line?

Question

Will JS auto semi-colon insertion place a semi-colon at the end of for(...) like I've placed in the following example or is it safe to break the bracket onto a new line with for loops?

for(...);
{
   ...
}

I've found plenty of info saying what is affected, but nothing specific to my question, which leads me to believe it may not be affected, but I would like to find a concrete answer.

Personally, I prefer not to break onto a new line with brackets like this but the question has been raised ;)

I've never run into a situation where I couldn't break curly braces onto the next line. (maybe someone could fill me into where you cannot?) — pattmorter, Jul 21 '14 at 15:08
@pattmorter When returning an object literal, you get unexpected results. `return { foo: 'bar' };` returns an object, whereas `return{foo:'bar'}` returns undefined because of ASI. — ahruss, Jul 21 '14 at 15:10

Such a for loop is safe. Semicolons will never be inserted in places where they would create empty statements.
