emacs: avoid weird package.el breakage with newish packages I've been toting around this package.el from 2009 or so, and something in the package format seems to have changed that broke me. Thanks to some related diagnostics by Lucas, I've grabbed the last package.el that worked with emacs 23 and stashed it here. This seems to work, modulo some things (notably js2-mode and smex) now seem to require emacs 24 if you install them using package.el, so this will end up being brittle on my last couple of emacs23 machines.
