iOS 9: Language Switching with Bluetooth Keyboard

It appears that with iOS 9 Apple has changed the standard hardware keyboard shortcut for switching among keyboard layouts.  Instead of the Command + Space used forever by earlier versions of OS X and  iOS, it is now Control + Space.

(This is now also the default shortcut for keyboard switching in OS X  10.11)
