I don't think you are missing anything obvious as for the ":results
value" case, I get the same thing.  In fact, for ":results output", I
don't actually get any output!  I'm not sure why.  I wonder if there
is a dependence on the version of Octave?  I'm using a fairly old
version (3.0.x instead of 3.2.x).
