Simplifying split-fancy rules

Simplifying split-fancy rules

[Jake Colman]

Can the following split-fancy expressions be combined in someway since they
all end up in the same place?

        (any "ding@gnus.org" "INBOX/Emacs/ding")
        (any "ding@gnus.com" "INBOX/Emacs/ding")
        (any "ding@hpc.uh.edu" "INBOX/Emacs/ding")
        (any "ding@ifi.uio.no" "INBOX/Emacs/ding")

You could use (regexp-opt '("ding@gnus.org" "ding@gnus.com" "ding@etc."))
to get a single regexp that matched all of those strings.

That is pretty cool!.  I guess I can run that once in *scratch* to examine
the results and hard-code the answer in nnimap-split-fancy directly.  

Thanks!
