That is not exactly what I meant. I meant if the data structures 
contains information that are useful for save/restore.

But I did not look close at it. The data structures in winner.el may be 
that too. I took a look at winner-currents and maybe that contains the 
information needed.

However I do not know if there is a way to save it. It contains the 
information needed in something that looks like #<window-configuration> 
when trying to print it. Is there a way to print this so that it can be 
saved?

BTW, winsav.el has a little bit different focus, solving a problem that 
I could not find a way to solve easily: Injection of a window 
configuration into a window. The ability to save and restore window 
configuration on a frame is just a byproduct.
