Further corrections to solve this problem and make 10 todo testcases succeed.

Thanks, Dmitry!
The usage of flag 0x8000 explains much.
I noticed that it is used not only for windows with WS_CHILD style,
but actually, it seems, for all windows (as certified by msg.c
tests and observations in Windows with, e.g. Spy++).

I prepared and sent to wine-patches the attached patch which
makes 10 (actually, 12 due to uncommenting earlier failing parts)
msg.c tests (with different kinds of windows) succeed.
Among them there is the testcase related with this bug and bug 4964.
Let us hope that the patch is accepted, so these 2 problems can be closed.
