OK, I've installed this change.  I notice that sometimes Fcar and Fcdr
are used instead of XCAR and XCDR eg.

this change:

      if (NILP (norecord)  && !EQ (buffer, XCDR (XCAR (Vbuffer_alist))))

in window.c:

                  w->buffer = Fcdr (Fcar (Vbuffer_alist));

When is it ever better to use the latter?
