Somebody who says "this commit is mine, and its author is this other
person" is not making any sense. The resulting commit can either have
that person (i.e. the committer) as the author, which is what the "claim"
option means, or it can have the person named with --author as the author,
but both cannot be true at the same time.
When you introduce a new option, sometimes it cannot sanely be used with
an existing option. In such a case, two options (the new one and the
existing one) are called mutually exclusive. And you add some code to
catch an user error to use them together.

How are the existing tests that try "commit -c" do this? I do not think
there is any here-text redirect into "git commit".
It is sometimes easier to show by example than by giving nudging words
that only show direction, so here is a suggested rewrite on top of your
patch. I am not very happy with the option name "mine" either, but at
least I think this gets the semantics right.
