bizarre parameter wrapping when followed by block comment

[srawlins]

I don't generally check in code like this, but was commenting out a method's implementation and writing in a new one, and got some weird formatting. Here's a simple repro that works on DartPad:

int foo(List<int> list) /*
1234567     14     21     28     35     42     49
  */
    => 7;

formats to:

int foo(
        List<int>
            list) /*
1234567     14     21     28     35     42     49
  */
    =>
    7;

I think the =>\n7 is covered in other bugs... but the newline before List<int> and the newline before list each seem weird. Or at least one of them is. Note that if you remove even one character from the comment text, both of those newlines disappear.

Yeah, that's pretty wonky.
