[PATCH v2 1/7] log: drop "--cc implies -m" logic

[Jeff King <peff@peff.net>]

This was added by 82dee4160c (log: show merge commit when --cc is given,
2015-08-20), which explains why we need it. But that commit failed to
notice that setup_revisions() already does the same thing, since
cd2bdc5309 (Common option parsing for "git log --diff" and friends,
2006-04-14).
