bug#902: select-active-regions only half-working

Whether it should or not is very debatable.  Historically, Emacs has
always reuqested the user to select with the mouse or use M-w for that,
and I have seen no evidence that people usually expect Emacs to copy the
region to the X11-selection more eagerly.

Your suggestion might please some people, but I do not think it
should be used by default.  So I suggest you turn your code into
a global minor mode.

I'm not sure I understand.  If it relates to the current code (as
opposed to yours), then please post a separate bug report for it (and
include a recipe, of course).
