octave_value::octave_idx_type_vector_value () "flattens" array

[c.]

Hi,

I'm trying to extraxt an array of index_type from a map field.
If I do:

 tt =  m.contents ("t").octave_idx_type_vector_value ();

tt is "flat" i.e. it has only one dimension, while to maintain the shape I have 
to do

 tt =  m.contents ("t").octave_idx_type_vector_value (true,true,true).reshape 
(m.contents ("t").dims ());

which is very ugly. Does anyone know why it is so? I can't seem to find a 
reason why the shape should be lost
when invoking "octave_idx_type_vector_value ()" …

c.
