Type printing isn't consistent

Compare List vs scala.collection.immutable.List:

Welcome to Scala.next (pre-alpha, git-hash: unknown)  (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_121).
Type in expressions to have them evaluated.
Type :help for more information.
scala> List(1, 2.0)
val res0: List[Double] = List(1.0, 2.0)
scala> List(1, 2.0, "abc")
val res1: scala.collection.immutable.List[Int | Double | String] = List(1, 2.0, abc)

Re-opening since the issue is about the printing as @dwijnand said. I think we need some logic to elide prefixes when pretty-printing.

Btw, just tried master and this is fixed:

scala> List(1, 2.0, "abc")
val res0: List[Any] = List(1, 2.0, abc)

scala> List(1, 2.0)
val res1: List[Double] = List(1.0, 2.0)
