Fixes #479

LGTM 👍

Generally, for lambdas, according to kotlin styleguide, this rule should format either to:

foo.func { param1, param2 ->
    doSomething()
    doSomething2()
}

or, if lambda params can't fit in max line:

foo.func { 
    param1, 
    param2
    ->
    doSomething()
    doSomething2()
}

Thanks; I did notice that as well. I'll open up another issue about moving params to the same line as the open bracket. It might be difficult to have it not conflict with the max_line_length rule. It looks like IntelliJ only moves the params if they're on the same line as the arrow, so we can follow that rule as well.
