bug#9925: 24.0.91; Maxmized, minimize, restore: emacs window hides under taskbar

[Juanma Barranquero]

>> 1) Move Windows XP taskbar to left side of screen.
>> 1) Run "emacs -Q"
>> 2) Click the maximize button (in the window title bar).
>> 3) Click the minimize button (in the window title bar).
>> 4) Click the emacs taskbar button.

>> Actual Result:
>> Emacs window is shoved to the left-hand edge of the screen, partly obscured 
>> behind the taskbar.

> I testing this issue on Windows 7 and got the same results.  This is not
> limited to Windows XP.

I can not reproduce it on Windows 7. After 4), Emacs uses the full
screen, minus the left-side taskbar, which is not obscured.
