The selected_window nil hack assures that point swapping is inhibited
until selected_window is set to some other value. Our change assures
that point swapping is inhibited only for the first invocation of
Fselect_window. If Fselect_window is called back via Fselect_frame,
point _is_ swapped. This might even be TRT, but it does not preserve
the current behavior.

If selected_window is no more set to nil, the crash in its present form
will disappear. The question is whether the change will change the
current behavior in the non-crashing case. Using a global variable, one
can emulate the current behavior without running into the crash.
