You have to call 'window-state-get' with the WRITABLE argument
non-nil, like (window-state-get nil t).  Otherwise, it gets you
markers just like 'current-window-configuration'.

Note that I did not disregard the remainder of your mail but please
let's continue the discussion after you tried my suggestion.

Thanks, martin
