[PATCH] send-email: Fix documentation of --signed-off-by-cc option

From: Namhyung Kim <redacted>

The man page says it'll control the Cc: lines being added also,
but this is not true.

Correct, but I'd urge you to step back and look at all the options.
Cc lines in the body (called bodycc) are parsed: see
git-send-email.perl:1361.  By default, everyone (cc, author, self,
sob, bodycc) is cc'ed by default.  You can turn off each of these
individually using --supress-cc which can take values
(all|cccmd|cc|author|self|sob|body|bodycc).  As you can see from
git-send-email.perl:400, the real purpose of --signed-off-by-cc is to
override a sendemail.suppresscc=sob; however, it can't override any
stronger values of suppresscc (body, all).  So, it's mostly a
no-option, and there is no corresponding --[no-]bodycc-cc.  Overall,
the way out of this horrible mess of options is to deprecate
--[no-]signed-off-by-cc, and modify --supress-cc to have a
--no-suppress-cc counterpart, just like --[no-]suppress-from.

Thanks.
