credit only to Jim Meyering and adjust the copyright dates. Do not include <limits.h>, <stdio.h>, <sys/types.h>, <stdlib.h>, <unistd.h>, "pathmax.h". Instead, include "xgetcwd.h" (first) and "getcwd.h". (INITIAL_BUFFER_SIZE): Remove. (xgetcwd): Rely on getcwd, since we now depend on a reliable one.
