Insert line breaks between `Multiple Parameter Lists`

[gbasler]

Unfortunately this function

  def mergeMapsCombiningValueMaps[A, B, C](collisionFunc: (C, C) => C)
                                          (m1: Map[A, Map[Seq[B], C]], m2: Map[A, Map[Seq[B], C]]): Map[A, Map[Seq[B], C]] = {
    mergeMaps(m1, m2)((m11, m22) => mergeMaps(m11, m22)(collisionFunc))
  }

gets reformatted as:

  def mergeMapsCombiningValueMaps[A, B, C](collisionFunc: (C, C) => C)(m1: Map[A, Map[Seq[B], C]], m2: Map[A, Map[Seq[B], C]]): Map[A, Map[Seq[B], C]] = {
    mergeMaps(m1, m2)((m11, m22) => mergeMaps(m11, m22)(collisionFunc))
  }

I would prefer keeping the line breaks as they were because then this monster takes at least a bit less space...
A configuration option that a) either always inserts line breaks or b) inserts line breaks if the line is longer than a specific lenght would be handy in this case.

def mergeMapsCombiningValueMaps[A, B, C](collisionFunc: (C, C) => C)(m1: Map[A, Map[Seq[B], C]], m2: Map[A, Map[Seq[B], C]]): Map[A, Map[Seq[B], C]] = {
    mergeMaps(m1, m2)((m11, m22) => mergeMaps(m11, m22)(collisionFunc))
  }

In 0.2.4 can be rewritten as:

def mergeMapsCombiningValueMaps[A, B, C]
  (collisionFunc: (C, C) => C)
  (m1: Map[A, Map[Seq[B], C]], m2: Map[A, Map[Seq[B], C]]): Map[A, Map[Seq[B], C]] = {

  mergeMaps(m1, m2)((m11, m22) => mergeMaps(m11, m22)(collisionFunc))
}
