bug#69093: window-state-put doesn't update current buffer

[Juri Linkov]

Martin, could you help to understand what is missing in
'window-state-put' that it doesn't set the current buffer
correctly like 'set-window-configuration' does.

For example, here the message says that the current-buffer
and point still have old values coming from the old buffer
that was current before calling 'window-state-put':

(let (ws)
  (info)
  (setq ws (window-state-get nil 'writable))
  (quit-window)
  (window-state-put ws nil 'safe)
  (message "! %S %S %S" (point) (current-buffer) (window-buffer)))

However, 'set-window-configuration' works correctly
and sets the restored buffer as current:

(let (wc)
  (info)
  (setq wc (current-window-configuration))
  (quit-window)
  (set-window-configuration wc nil t)
  (message "! %S %S %S" (point) (current-buffer) (window-buffer)))
