Hi,

Here's the latest version from mercurial 1.3.

#compdef hg

# Zsh completion script for mercurial.  Rename this file to _hg and copy
# it into your zsh function path (/usr/share/zsh/site-functions for
# instance)
#
# If you do not want to install it globally, you can copy it somewhere
# else and add that directory to $fpath. This must be done before
# compinit is called. If the file is copied to ~/.zsh.d, your ~/.zshrc
# file could look like this:
#
# fpath=("$HOME/.zsh.d" $fpath)
# autoload -U compinit
# compinit
