Re-titling report to reflect true issue.  I did the coding for "ColorOrder" property back when it was first implemented in Octave and Matlab.  Apparently Matlab has gone on to implement 4 new graphics properties for Line objects.

Getting Matlab compatibility here will be something of a project as the properties will need to be added first to graphics.in.h and then the updaters may need to be customized which isn't always straightforward.

I changed the item group from "Matlab Compatibility" to "Incorrect Result" because I thought that this behavior was just wrong.  But now I see that Matlab behavior changed a few years ago and I believe Octave implements the previous Matlab behavior so I'm changing it back to Matlab Compatibility.

For anyone who wants to work on this change, note that the behavior of the ColorOrderIndex property in Matlab also changed.

In Matlab, the following code sets the lower line to green.

plot([1 2; 4 5],'LineWidth',3)
C = get(gca, 'colororder') ;
C(1,:) = [0 1 0];
set(gca, 'colororder', C)

In Octave this doesn't work.
