Hi Pascal,

As Katsumi Yamaoka-san has written, you have to use either a string in
the first element of each `split', or one of the supported keywords
(extending the keyword list is easy too, but it's not necessary here).

The above split could be written as:

    '(| (: nnmail-split-fancy-with-parent)
        (from ".*cron daemon.*" "mail.cron")
        (to ".*vms-list@voynich.net.*" "mail.voynich")
        (from ".*gentoo.*" "mail.gentoo")
        (from ".*zenith.*@zenit.org.*" "mail.zenith")
        (to ".*\\(lisp.it\\|slime.*@common-lisp.net\\).*" "mail.lisp")
        (from ".*\\(@freelance.com\\|@dice.com\\).*"
        "mail.jobs"))))

The nice thing about keywords is that they match more than one type of
email header:

,----[ Gnus manual.  Node: Fancy Mail Splitting ]-----------------------
|
| Predefined entries in `nnmail-split-abbrev-alist' include:
|
| `from'
|      Matches the `From', `Sender' and `Resent-From' fields.
|
| `to'
|      Matches the `To', `Cc', `Apparently-To', `Resent-To' and
|      `Resent-Cc' fields.
|
| `any'
|      Is the union of the `from' and `to' entries.
|
`-----------------------------------------------------------------------

The `from' keyword is probably less useful if you only want to split on
the "From:" header, but the `to' keyword is my all times favorite :-)
