Details:

This is a continuation of the bug and fix in this patch report
(https://savannah.gnu.org/patch/?8152#postcomment).  Previously, Octave was
segfaulting when an attempty was made to use a null index on a class object. 
For example


x = foo ()
y = x()


The classdef file foo.m is attached to this report.  In this cset Octave was
changed to issue an error and stop segfaulting
(http://hg.savannah.gnu.org/hgweb/octave/rev/274b52724931).  This is certainly
preferable.

However, for ultimate Matlab compatibility Octave should simply return the
base object x rather than issue an error.  Testing of that was done in the
patch cited.

Probable solution is something like  retval = this, but using the correct
syntax.
