;; Todo, minor things:
;;
;; o Don't require half of Gnus -- backends should be standalone
-;; o Support escape characters in `message-tokenize-header'
;; o Verify that we don't use IMAP4rev1 specific things (RFC2060 App B)
;; o Dont uid fetch 1,* in nnimap-retrive-groups (slow)
;; o Split up big fetches (1,* header especially) in smaller chunks
be called with the headers narrowed and should return a group where it
thinks the article should be splitted to.")
