Updates regarding fts_close(3):

1) The close(2) return value and errno are ignored.
2) The errno is set by fchdir(2), not by chdir(2),
which has much less potential for errors.
3) Use .Rv -std.
While here, remove STANDARDS.  Keith Bostic added that hope in 1990
and tweaked the wording in 1993, but it didn't come true since then.
