          Severity: minor

For consistency with Windows (95 and 2000, at least), when you press F1 on a 
control, it should not immediately send a WM_HELP message to the control as it 
does now (see process_cooked_keyboard_message() in windows/message.c). Rather, 
it should _post_ an 0x4d message to itself with wParam=0 and lParam=0. 
DefWindowProc should then handle 0x4d by sending a WM_HELP message.

0x4d seems to be undocumented but is still useful to third-party apps: they can 
swallow 0x4d messages in their message loop to prevent WM_HELP messages from 
being sent.
