[PATCH v1 4/4] name-rev: remove "--stdin" support

[Junio C Hamano <gitster@pobox.com>]

As part of Git 3.0, remove the hidden synonym for "--annotate-stdin"
for real.  As this does not change the fact that it used to be
called "--stdin" in older version of Git, keep that passage in the
documentation for "--annotate-stdin".
