The behavior of Emacs 22 is an unintended and (AFAICT) undocumented
consequence of the delete-selection-mode implementation---basically a
bug, since it had nothing to do with deleting selections.  We might
eventually re-implement this as an optional behavior, but that would be
a new feature (it will certainly not be the default behavior, since it
is very non-standard for graphical applications).

So I do not regard this as a regression, or even a bug.  I'm setting the
severity to wishlist, because there are better things to work on.  Do
not play with the severity---that will not increase the likelihood of
this feature being implemented.
