5813 behavior would be very odd on Windows where the usual policy is
5816 On X, if the mouse happens to be over the raised frame, it gets
5817 input focus anyway (so the window with focus will never be
5818 completely obscured) - if not, then just moving the mouse over it
5819 is sufficient to give it focus. On Windows, the user must actually
5820 click on the frame (preferably the title bar so as not to move
5821 point), which is more awkward. Also, no other Windows program
5822 raises a window to the top but leaves another window (possibly now
5823 completely obscured) with input focus.
5825 Because there is a system setting on Windows that allows the user
5826 to choose the point to focus policy, we make the strict semantics
5827 optional, but by default we grab focus when raising. */
