bug#33871: 27.0.50; Revert Dired window saved in window configuration

[martin rudalics]

> So now here is the final patch:

For 'window-point-context-set' I'd rather write something like:

  Call function specified by `window-point-context-set-function' for every
  live window on the selected frame with that window as sole argument and
  that window's buffer current.  The function called is supposed to return
  a context of the window's point that can be later used as argument for
  `window-point-context-use'.  Remember the returned context in the window
  parameter `context'.

+function is called with two agreements: the window and the context data
                             ^^^^^^^^^^

I still don't get why you use 'with-current-buffer' here.  IIUC usually
a buffer does not have 'window-point-context-set-function' set and so a
simple

(buffer-local-value 'window-point-context-set-function (window-buffer w))

should suffice.
