vc-do-async-command: Ellipse later lines in multiline arguments

* lisp/emacs-lisp/cl-print.el (cl-print-expand-ellipsis): Bind
inhibit-read-only to t.
* lisp/vc/vc-dispatcher.el (require): Require cl-print at
compile time.
(vc-do-async-command): When printing command arguments that
contain multiple lines, use cl-prin1 with cl-print-string-length
bound in order to ellipse lines other than the first.
Switch the outer quotation marks to single quotation marks.
