Does the USB standard specify how a charger is to behave? What does it
have to say about the fact that Motorola chargers short the Data+ and
Data- pins (according to pinouts.ru)?

http://en.wikipedia.org/wiki/Usb#Power tells, that this is the "Battery
Charging Specification". This way no electronics is needed in a simple
Charger.
The wikipedia article (especially the power section" is a highly
recommended read for all the people discussing here since it covers most
of the topics discussed.

Does the required "standard" cable, when connected to a charger, need
to have 5 pins at both ends?

http://en.wikipedia.org/wiki/Usb#Types_of_USB_connector should have the
answer. And to be honest. I've just now read it...
