(desktop-save): Ensure parameter is expanded and ends with a slash before

assigning it to desktop-dirname and default-directory.
(desktop-read): Put buffers existing prior to evaluating the desktop (and not
reused) at the end of the buffer list.
(desktop-create-buffer): Don't update desktop-first-buffer for old desktop
files.
