Hmm, it is a little unfortunate that the docstrings of those hooks don't
say... Both of them are called with the same arguments: ACTION (which
can be a symbol like move, delete, crosspost, or copy), DATA (which is
the header data as returned by `gnus-data-header'), FROM-GROUP (where
the article's coming from), TO-GROUP (where it's going), and
SELECT-METHOD, for the current select method.

See, for example, the body of `gnus-summary-move-article' for both the
move hook and the delete hook in action.

Hope that helps,
Eric
