From my experience, it seems that POV (or, to be precise, MegaPOV 1.2.1, but I
guess there shouldn't be a difference there) for Unix does not issue an exit
code when terminating prematurely, although the documentation states it should.

To render a scene that requires other scenes to be rendered first, I set up a
shell script as folows:

    megapov -D MyScene_pre.ini && megapov -D MyScene.ini

Now when MegaPOV reports an error in the first scene, I experience that the
second MegaPOV command is still started.

The same happens when I decide to terminate the render of the first scene by
issuing a SIGTERM to the MegaPOV process.

Am I doing something wrong, or is this just not supported in the Unix version?
