create_set/intersection always returns a row vector.
unique/intersect/union returns a vector of the same orientation
as the input, with a preference for column vector if given a matrix.

create_set does not accept 'rows' argument for unique rows.

union is not part of octave-forge.

The octave-forge functions were compatible with R11 I think.  I haven't
checked recently.
