inline def is not inlined when it has two parameter lists, one with a repeated parameter and one with a default parameter

[smarter]

This is a very weird combination that I haven't been able to reduce further:

object Test {
  inline def foo(first: Int*)(second: String = "") = {}

  def test = {
    foo(1)()
  }
}

The body of test after typer is:

        {
          val first$1: Int* = [1 : Int]: Int*
          Test.foo(first$1)(Test.foo$default$2(first$1))
        }

Notice that foo hasn't been inlined away.
