I think it is much clearer if you do not say what does _not_ affect
things, but instead say what does.  So let's do this instead.

        --signoff::
                Add Signed-off-by line by the committer at the end of the commit
                log message.


And no other changes.

By making it clear that signoff is about the committer, it would be clear
that --author (or GIT_AUTHOR_NAME environment variable) would not affect
it.
