Re: What is restore_window_configuration in read_minibuf (minibuf.c) for?

Indeed.  I think we should remove it, but for that we need to replace it
with something that does the part we want to keep (e.g. making sure
that the buffer from which the minibuffer was "called" is
selected&visible again).

Maybe the restoration of some previous minibuffer is OK (e.g. when you
use `M-x` from within `M-:` you do want the outer minibuffer to be
restored when you leave the inner one), and you just need to adjust it
after the fact in the rare cases where it results in an undesirable
state (e.g. if that minibuffer was already displayed elsewhere).
