I think it does make sense to document this with the --author/--committer
options.
That wording would however make me assume that --all-match could also
be used, so that
git log --all-match --author ceder --author cibot
would list nothing (since there are no authors that match both
"ceder" and "cibot" in this codebase). That isn't the fact, though.
It seems to list all commits that have either ceder or cibot as author,
just as if I had not used --all-match.
As a reader of the man-page, I would prefer to have the exact list
of options in the documentation. (I realize that it will make it harder
to maintain.)
