I've checked in some changes that should (fingers crossed) fix the
"empty selection" problem.  This also eliminates the use of
x-set-selection to buffer variables, as you suggested.  Now, Emacs
copies strings out explicitly in the command loop and in
`deactivate-mark'.

I added a new value to `select-active-regions', `lazy' (the default),
which means to set the selection only when used, as described in an
earlier email.  Any other non-nil value gives something similar to the
original behavior of select-active-regions.
