Thanks, I've updated the post to include this info.

I'll add that you can download the git completion functions if needed from http://zsh.cvs.sourceforge.net/viewvc/*checkout*/zsh/zsh/Com...

I've got a few hook scripts in my dotfiles here: https://github.com/cypher/dotfiles/tree/master/git-hooks

But you can also take a look at the `.git/hooks/` directory in any git repo, it includes a lot of sample hooks.

thanks for the tip!
