With some modification the coreutils change_file_owner and
change_dir_owner functions (in src/chown-core.c) could be the core of

DEFUN ("set-file-owners", Fset_file_owners, Sset_file_owners, 2, 3, 0,

If OWNER or GROUP is nil then skip setting that attribute.
Return t on success, else nil.  */)
  (filename, owner, group)
     Lisp_Object filename, owner, group;
{
