octave:1> size ([])
ans =

   0   0

octave:2> size ([], 1:5)
ans =

   0   0   1   1   1


It should be zero for all dimensions. This inconsistency makes trouble when
appending in different directions.


octave:1> a = b = c = [];
octave:2> a(end+1, :, :) = 1
a = 1
octave:3> b(:, end+1, :) = 2
b = 2
octave:4> c(:, :, end+1) = 3
c =

ans(:,:,1) = 0
ans(:,:,2) = 3


Why are a and b only one element but c is two elements? All should be one
element.
