The issues aren't quite fresh in my memory, but IIRC the three cases we
need are "never save", "always save" and "only save for intra-session
restore because it can't be saved to disk".
But the above seems to do the reverse, i.e. it provides a "only save
inter-session but not intra-session", which is rather weird.  IOW, I'd
have expected the meaning of `state' to be the opposite (save for
current-window-configuration or when `ignore' is non-nil, but not when
ignore is nil since it may un`read'able).
Am I missing something?
