If there is no option or hook, if guess I could just modify the

1. Stefan can probably steer you as to how to do what you want with a recent
version of vanilla Emacs.

I ended up modifying `minibuffer-completion-help'. There doesn't seem to be a way around that.

2. An alternative is to use Icicles.  Then all you need to do is bind
`icicle-sort-comparer' to nil around the call to `completing-read'.  A nil value
means do not sort.  (You can also customize `icicle-sort-comparer' to use any
default sort order you like.)

Thanks, I will look into that. Or do you replace the whole completion mechanism?
