But does the replacement article get the old article number,
or a new number?  Which you do depends on whether you think
readers of the old message should see the new article, or not.

It sure would be nice to go back and correct errors in a posting
without anyone having to see the article a second time.  Of course
if you *want* them to see it again, you can cancel and start over...

Perhaps the header should be "Replaces: message-id" and it should
overwrite the old article without removing anything?
