Details:

When displaying a classdef object, all properties are printed including Hidden
and Protected properties.  This is not what Matlab does, nor is it what the
properties() function does which is also confusing.

Consider the following classdef file in testprop.m (also attached):


classdef testprop

        properties
                testprop = 0;
        end

        properties (Access = protected)
                protectedtestprop = 0;
        end

        properties (Hidden = true)
                hiddentestprop = 0;
        end

end


Code to reproduce.


octave:1> x = testprop
x =

testprop object with properties:

     hiddentestprop: [1x1 double]
  protectedtestprop: [1x1 double]
           testprop: [1x1 double]

octave:2> properties (x)
properties for class testprop:

  hiddentestprop
  testprop



The fact that the properties() function shows hidden properties was separately
reported at bug #55766.

In terms of architecture, the disp() function for class objects should
probably not implement it's own logic.  Instead it should probably call to the
underlying function that implements properties() so that it stays in sync with
fixes there and there is no code duplication.
