Those variables (plus -confirm) are let-bound by Emacs' own higher level completion functions, and I think it'd be cleaner if you did the same -- or just set your own my-completion-table and -predicate variables, since you're passing their values explicitly to all-completions anyway. -- Kevin Rodgers
