* ediff-ptch.el (ediff-file-name-sans-prefix): treat nil as an empty
	string.
	(ediff-fixup-patch-map): better heuristic for intuiting the file names
	to patch.
	(ediff-prompt-for-patch-file): more intuitive prompt.

	* ediff-util.el: use insert-buffer-substring.

	* ediff-vers.el (cvs-run-ediff-on-file-descriptor): bug fix.

	* viper-cmd.el (viper-change-state): don't move over the field
	boundaries in the minibuffer.
	(viper-set-minibuffer-style): add viper-minibuffer-post-command-hook.
	(viper-minibuffer-post-command-hook): new hook.
	(viper-line): don't move cursor at bolp.

	* viper-ex.el (ex-pwd, viper-info-on-file): fixed message

	* viper-init.el: add alias to make-variable-buffer-local to avoid
	compiler warnings.

	* viper-macs.el (ex-map): better messages.

	* viper-utils.el (viper-beginning-of-field): new function.

	* viper.el: replace make-variable-buffer-local with
	viper-make-variable-buffer-local everywhere, to avoid warnings.
