;; - renaming bookmarks in gnus-bookmark-bmenu-list
;; - better (formatted string) display in bmenu-list
-;; - Fix use of `split-string' and `assoc-string' for compatibility with Emacs
-;; 21 and XEmacs 21.4.
;; - Integrate the `gnus-summary-*-bookmark' functionality
;; - Initialize defcustoms from corresponding `bookmark.el' variables?
