[Octave-bug-tracker] [bug #51754] MEX interface returns odd NULL objects

Follow-up Comment #5, bug #51754 (project octave):

Seems reasonable to be Matlab-compatible in this regard as it is generally
easier on the programmer if the interpreter stops as close to the location in
the code where an error occurred.  Having an undefined value and propagating
it through several m-files before something eventually fails is unfriendly.

Alas, it also creates some more work.  The documentation and code examples in
Appendix A : External Code Interface now need to be updated as helloworld.cc,
myhello.c, mex_demo.c all produce errors now when called with multiple
outputs.
