Was this change deliberate to remove the check of result? If so, I don't 
see where else the result of the message can be properly checked.

The result is sent back to the application in the WM_ENDSESSION message 
and checked in the if branch to exit the loop, and then again right 
outside the loop to abort the Windows shutdown.

if (SendMessageTimeoutW( *phwnd, WM_QUERYENDSESSION, 0, 
0, send_flags, 0, &result))
                 {
                     DWORD_PTR dummy;
                     SendMessageTimeoutW( *phwnd, WM_ENDSESSION, result, 
0, send_flags, 0, &dummy );
                     if (!result) break;
                 }
             }
             HeapFree( GetProcessHeap(), 0, list );

if (!result)
                 return TRUE;

Yes, you are right. I obviously didn't spend enough time reading your patch.
