Repair bug #2694 concerning an ARRAY[] construct whose inputs are empty
sub-arrays. Per discussion, if all inputs are empty arrays then result
must be an empty array too, whereas a mix of empty and nonempty arrays
should (and already did) draw an error. In the back branches, the
construct was strict: any NULL input immediately yielded a NULL output;
so I left that behavior alone. HEAD was simply ignoring NULL sub-arrays,
which doesn't seem very sensible. For lack of a better idea it now
treats NULL sub-arrays the same as empty ones.
