	Please consider the revised patch MIMEd.

	* lisp/tar-mode.el (tar-header-extractable-p): New function.
	(tar-untar-buffer): Use it; or use the value of the new optional
	argument instead.

	* lisp/emacs-lisp/package.el (package-untar-buffer): Use
	tar-header-extractable-p.
	(package-tar-file-info): Consider the second file name in the
	archive if the first one has no directory component.
