The "Required Back End Functions" node of the manual says:
`(nnchoke-request-article ARTICLE &optional GROUP SERVER TO-BUFFER)'
...
     If it is at all possible, this function should return a cons cell
     where the `car' is the group name the article was fetched from,
     and the `cdr' is the article number.  This will enable Gnus to
     find out what the real group and article numbers are when fetching
     articles by `Message-ID'.

I interpreted this to mean that the backend is supposed to search all
groups if the Message-ID isn't found in the given group, so that's
what nnmaildir does.  [^] in the *Summary* buffer and [C-c ^] in the
*Article* buffer will find messages in other groups.  Doesn't this
work with other mail backends?
