Add docstrings, in several cases by converting existing
comments.  (Bug#30085)
(cua--last-killed-rectangle): Update comment.

* lisp/simple.el (visual-line-mode): Only save values once, even
if the mode is switched on twice (bug#43730).  This makes both
previously set local values for variables like truncate-lines, as
well as default values for truncate-lines restorable.
