* mouse.el (mouse-region-delete-keys): Deleted.

* simple.el (delete-active-region): New option.
(delete-backward-char): Implement in Lisp.
(delete-forward-char): New command.

** completion-at-point is now an alias for complete-symbol.
** mouse-region-delete-keys has been deleted.
+
+** Deletion changes
+
+*** New option `delete-active-region'.
+If non-nil, C-d, [delete], and DEL delete the region if it is active
+and no prefix argument is given. If set to `kill', these commands
+kill instead.
+
+*** New command `delete-forward-char', bound to C-d and [delete].
+This is meant for interactive use, and obeys `delete-active-region';
+delete-char, meant for Lisp, does not obey `delete-active-region'.
+
+*** `delete-backward-char' is now a Lisp function.
+Apart from obeying `delete-active-region', its behavior is unchanged.
+However, the byte compiler now warns if it is called from Lisp; you
+should use delete-char with a negative argument instead.
+
+*** The option `mouse-region-delete-keys' has been deleted.
