Right. That _extensions extension works, thanks for the pointer!

The only problem now is that my "normal" completions add a space after
the completion and that happens here as well. As I want to use these
completions as bases for further completions that means I have to
backspace and press <tab> again. I have no problem with the <tab> but
not adding a space would make things a bit faster. Alas I've not found
the right place to do that.

I have this

zstyle ':completion:*' menu select=2 interactive

if that helps.

Again thanks, much appreciated!
