[ESS-bugs] julia: TAB completion fails for emacs 23

[Vitalie Spinu]

I didn't bother implementing tab completion for emacs 23 a year ago,
because the completion mechanisms are very different and some other
features for julia worked only for emacs 24 anyways. I would bother even
less now as I completely lost interest in julia since then.
