AFAICS, such an approach would make deselection much less likely to work
consistently:  the way it's _supposed_ to work is that any pretty much
any command except for the special shifted versions should cause
deactivation -- and in emacs that's pretty much _every command_.
So to make it work "correctly", you need to modify all commands in
emacs!  [yikes!]

The method I showed earlier seems almost as simple, and has the
advantage that it's very unintrusive -- you only need to worry about the
commands which implement the special behavior -- and seems to work
pretty well.
