OK, I now did a quick test, and it works as advertised.

But I realized that the various ?zap options now get
increasingly inconsistent. The only sensible way out
is to merge the three ?zap progams into one, and possibly
move common stuff into a library.

I know this breaks backwards compatibility for scripts
which use ?zap, but I think we should do it before
doing a new dvb-apps release.
