`window-state-put' doesn't know anything about files.  It simply expects
the window's buffer to be there.  But we can easily replace

        (set-window-buffer window (get-buffer-create (car state)))

by, for example,

        (set-window-buffer window (or (get-buffer (car state))
                                      (get-buffer-create "*scratch*")))

If we saved and restored window-local buffer lists, we could show the
previous buffer on that window's list instead.

Two remarks: I never heard about `get-buffer-create' creating any files
or directories.  And, `window-state-put' reuses the name of the window's
buffer from the other session.  So if you have a buffer "foo" in the old
session and a completely different buffer "foo" in the new session, it
will show that other buffer instead.
