Addresses GB-112

Should the effect of calling `front/back` on a zero-sized `array` really be implementation defined i.e. require the implementor to define behaviour?

[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]

Proposed resolution:

Change "implementation defined" to "undefined"
