Avoid breaking non-trailing block comments.

Motivating example:
// column limit ------------------->
void ffffffffffff(int aaaaaa /* test */);

Formatting before the patch:
void ffffffffffff(int aaaaaa /* test
                              */);

Formatting after the patch:
void
ffffffffffff(int aaaaaa /* test */);
