The command now issues a big deprecation warning message and runs git-archive command with appropriate arguments. git-tar-tree $tree_ish $base always forces $base to be the leading directory name, so the --prefix parameter passed internally to git-archive is a slash appended to it, i.e. "--prefix=$base/".
