I'm not entirely sure.  I actually added a "get_minibuffer (0);" to
init_minibuf_once in my commit earlier on today, so perhaps the
"set_minibuffer_mode (minibuf, 0);" really belongs in that function.

I'm not quite sure in my own mind what should go into init_minibuf_once
and what into init_minibuf_once_for_pdumper.  I've taken as the
criterion what the comment there says:

  /* We run this function on first initialization and whenever we
     restore from a dump file.  pdumper doesn't try to preserve
     frames, windows, and so on, so reset everything related here.  */

, and thus put the creation of  *Minibuf-0* into init_minibuf_once.

It would be good to have a relatively simple fix for something in
minibuf.c, for once.  ;-)
