Well, if someone wants to see if he can find any problems with this,
it would be the patch below...

Note to maintainers: dunno if this should be applied right now, maybe
there are problems I don't see.

And if we find no problems or the solutions for them, we should of
course also change the docs. And decide about the standard way to form 
the namespace: `.<module>.<param>' or `<module>.<param>' or
`.zsh.<module>.<param>' or `zsh.<module>.<param>' or ... (I know that
you know that -- I just wanted to write them down to be able to have a 
look at them to find out which one I like the most; still don't know;
the ones with the dot at the beginning look a bit zstyle'ish, don't
they? the ones with the `zsh' are a bit longish... hm).


Bye
 Sven
