    _______________________________________________________

Details:

When calling nextpow2 with a vector, Octave currently uses the length of the
vector. On the other hand, Matlab computes the nextpow2 for each element of
the vector.


octave-cli-3.8.2> nextpow2 ([15])
ans =  4
octave-cli-3.8.2> nextpow2 ([15 15])  # is computing nextpow2 (length ([15
15])) 
ans =  1


I can fix this myself, but that is a backwards incompatible change (also, I
believe that Matlab behaviour here is saner but I am more used to nd signals).
