[wp-hackers] Issue with update-notify

[Gudlyf]

I saw from the Plugin/API wiki page at http://wiki.wordpress.org/Plugin/API that the 'publish_post' hook is
supposed to only kick in when a post is *first* published. However, with my update-notify plugin (that sends
an email out to a list when the blog gets a new post), I've had to fiddle around trying to get it to not mail
if an already published post gets edited. You can see from the latest version I have up at
http://www.gudlyf.com/index.php?p=357 what I've tried. It only works if you don't first save the post to
draft, then publish, so that's not going to work.

Is there another hook I'm supposed to use to only kick in on the initial publish of a post? Perhaps that wiki
entry is described incorrectly?

Thanks.
