i don't think its a fork, just an older snapshot of the package.el in
the bzr repository. (but newer than the one available to download on the
old ELPA site http://tromey.com/elpa/). I'm not sure why Marmalade
aren't linking to the most recent package.el, some incompatibilities
with Emacs 23 maybe?
