Thanks, all your patches is a nice improvement.  I have a question only
about the last patch.

This was just a plain bug.

So typing C-g in the *Completions* buffer will be the same as
typing C-g in the minibuffer?  This would provide more consistency.

I guess it's too late to allow all self-inserting keys in the *Completions*
buffer to be used either to add characters to the search string,
or to narrow completions interactively as if they were typed in the minibuffer,
because "q", "n", "p", "z" are already bound to other commands?
