I've now spent several days trying to get this right -- and am now
really fed up. My last solution almost worked but still had problems
with, e.g. zsh -c 'zsh -c "zsh -c echo\ <TAB>. Mainly due to the
somewhat weird backslash-in-quotes behavior. Also, I only had this for 
inserting unambiguous matches (do_single()), and the stuff for
unambiguous prefixes is even harder.

So, I *will* some day try to fix this, but I don't think I'll be able
to do this this week and next week I'll be away.

I'll have to find a completely different way for this...

Bye
 Sven
