bookmark.el and lisp/gnus/gnus-bookmark.el

[Karl Fogel]

Does anyone know why we have both 'bookmark.el' and 'gnus-bookmark.el'?

The latter says:

  ;; This file implements real bookmarks for Gnus, closely following the way
  ;; `bookmark.el' handles bookmarks.  Most of the code comes from
  ;; `bookmark.el'.

I'm not sure why GNUS bookmarks should live in a separate space from
other bookmarks, and my feeling is that they ought to be unified --
that is, the gnus-bookmark.el functionality absorbed into bookmark.el,
with compatibility shims to transfer people's ~/.gnus.bmk file
contents to ~/.emacs.bmk.  (Of course, I really mean whatever the
values of `gnus-bookmark-default-file' and `bookmark-default-file'
are, respectively.)

Thoughts?
