Oops, you are so right.  I downgraded and found that zsh-3.1.6-dev-21 trips 
over the same thing.  Sorry about this misinformation!

And in fact, I moved the look statement into the if-then-else construct
lately.  I guess I haven't use it then for a while and happened to notice
that it doesn't work anymore after my zsh-upgrade.  Stupid coincidence. :-(

Oohhh!  This is not very self-evident.  Maybe that should go into the FAQ?
I split the if-clause in two and now it works.  Thank you!

Thanks!

Thanks and sorry again!
 Andy.
