* bytecomp.el: Declare unread-command-char an obsolete variable.

	* vip.el (vip-escape-to-emacs, vip-prefix-arg-value,
	vip-prefix-arg-com): Use unread-command-event instead of
	unread-command-char; respect its new semantics.
	* simula.el (simula-electric-label): Same.

	* simula.el (simula-calculate-indent): Call backward-word with the
	appropriate argument.
