> the default completion in Emacs-23 is very close to partial-completion-mode


OMG, so it is!   I've been using partial-completion-mode so long I can't
remember why I turned it on.  What's even stupider is that I've never
actually used the "partial" feature.  Thanks very much for the
enlightenment.
