Recommended way to force a posted article into drafts?

[Lloyd Zusman <ljz@asfast.com>]

I'm using the latest (or near-latest) CVS version of gnus.

In certain newsgroups, I want to be able to review and revise all of
my articles before they actually get posted.  In these special groups,
I map `\C-c \C-c' to my special function for deferring the post.  What
this function does is to simply force the article into my `drafts'
folder. `\C-c \C-c' remains mapped to `message-send-and-exit' in all
the other groups (including `drafts').

My question is this: is the following function the recommended method
for forcing an article into `drafts'?  (this is a stripped-down version
of my actual function, showing only the essentials):

  (my-defer-posting ()
    (save-article)
    (kill-buffer (current-buffer)))

This seems to work just fine and is consistent with how drafts work in
general ... but just in case, I want to double-check in case there's
something special that I should do in addition to this or instead of
this.

Thanks in advance.
