Teach --stdin option to "log" family
Move the logic to read revs from standard input that rev-list knows about from it to revision machinery, so that all the users of setup_revisions() can feed the list of revs from the standard input when "--stdin" is used on the command line. Allow some users of the revision machinery that want different semantics from the "--stdin" option to disable it by setting an option in the rev_info structure. This also cleans up the kludge made to bundle.c via cut and paste. Signed-off-by: Junio C Hamano <gitster@pobox.com>
