+** You can now set the variable `kill-whole-line' to `always', which
+makes `kill-line' (C-k) delete the entire line always, not just when
+the cursor is at the beginning of the line.  This behavior, as well as
+the existing kill-whole-line behavior, now only take effect when
+kill-line is called interactively, although this is a departure from a
+previous behavior in the case of setting this variable kill-whole-line
+to t.  It is almost certainly what has always been intended, and most
+likely the old way of doing things introduced bugs.
+
+The new function `historical-kill-line' ignores the `kill-whole-line'
+setting and always gives the historical behavior of only killing to
+the end of the line.  This function is bound to Sh-C-k, so that the
+kill to end of line behavior is available, even when `kill-whole-line'
+has been customized.

+not have an accelerator specified, one is created dynamically, using
