Regression in `Changed#uptodate`? about util

Thanks for reporting this.

As far as I can tell Changed is no longer used by sbt. So I think we will deprecate it during 1.x.

Here's how you can port bleh:

bleh := {
  import sbt.util.CacheImplicits._
  val f = Tracked.inputChanged[URI, Unit](streams.value.cacheDirectory / "bleh") {
    case (changed, in) => println(s"changed=$changed")
  }
  f(uri("http://bogus"))
}
