bug#34014: 25.2; binding down mouse event with modifier to mouse-drag-region does not work

[Adolf Mathias]

No, this does not work - it kills between the original mouse position
and the position where the S-mouse1 went down.

Funny is, it works on Emacs24 - probably because the mouse-drag-track
in mouse-stay-and-copy  keeps the S-drag-mouse-1 binding from
receiving events.

It seems that mouse-drag-track is broken, what concerns my
expectations to it. And it can be reimplemented, as I mentioned before
that I did - I just did not bother to reimplement the multiple-click
logic that is part of it.
