bug#33532: 26.1; set-window-configuration does not restore display start

Due to the buffer erasing part when reverting the buffer.

I think that Stefan's approach to restore windows' point markers does
that in a more sophisticated way.  I'll attach a patch.

But that patch does not address window configurations and states -
simply because it can't access them.  We need a different solution for
those.  And it obviously does not handle non-default reverters like
'dired'.
