Again, no support for window configurations and non-writable window
states.  But maybe it's possible to access all buffer's windows,
even windows in window configurations/states, and changes their
window points, including previous buffers' points in window
configurations/states.

BTW, I understand why reverting a dired buffer moves its point-marker to
the beginning of the buffer in the selected window window restored from
a window configuration.  But I don't understand why point-marker is
moved to the end of the dired buffer in non-selected window restored
from a window configuration.
