zsh auto completion in home dir

I used for years in openSuSE the:

#compdef w
 _files -W ~/work -/

function to auto-complete the directory names in my ~/work dir.

It does not work in Ubuntu zsh -v 4.3.11, when I hit TAB after w I got dire开发者_运维知识库ctories from my home directory.

What's different in Ubuntu?

Nevermind I found cdpath variable. I added in my config file

cdpath=( /usr ~ ~/work )

and it works :) Just cd somechar Tab. No more compdef functions.
