Thanks, this has now such a nice property that after typing TAB
that switches to the completions buffer, it's easy to switch back
to the minibuffer by typing S-TAB. But this works only when
completion-wrap-movement is non-nil.

It seems now completion-wrap-movement has no effect:
typing n, p, <right> or <left> eventually switches to the minibuffer,
where continuing typing these keys uses other commands.

Using S-TAB to scroll backwards also works nice.
The only difference with TAB is that while typing
several TABs reaches the end of the completions buffer,
typing more TABs wraps to the beginning of the completions
buffer, but S-TAB doesn't wrap to the end of the buffer.
