Actually the data argument should be all you need. It will contain
several of the important email headers from the message, if that's good
enough, and that it isn't good enough, it also contains the article
number, which is all you need to retrieve the whole article.

Part of the confusing thing about this is that it's hard to tell what
"the article" actually is. As far as Gnus is concerned, the article
number is the important thing. But when you say you want the "raw
article" passed to the function, what does that mean, exactly? A buffer
holding the article? The article as a string? Practically speaking, you
can use that data to do pretty much anything you wanted to do with the
article.

I know that's not that helpful...
