also look to parent classes for overloaded functions called through handles * ov-fcn-handle.cc (octave_fcn_handle::do_multi_index_op): Look for overloads in parent classes if none are found in the immediate dispatch class. * test/fcn-handle-derived-resolution: New directory for tests. * test/Makefile.am: Include fcn-handle-derived-resolution/module.mk.

function r = derived (n)
  s.a = n;
  p = parent (n);
  r = class (s, 'derived', p);
