Inconsistent Documentation concerning Utility Operator delay

[philippguertler]

This issue is about the delay operator to delay an observable until another observable is completed.
On this page http://reactivex.io/documentation/operators/delay.html it says that it waits until the other observable is completed.
However, in RxJava it only waits until the other observable starts emitting its items (this is documented here http://reactivex.io/RxJava/javadoc/rx/Observable.html#delay(rx.functions.Func1) under Parameters.
