I'm not too worried about those. I'd imagine that "--objects" becomes a
documented synonym for "--show-trees --show-blobs --show-commits
--show-tags", and then the usual interactions take over.

But...

Yeah, that's true. My biggest complaint is lack of an OR filter, but we
could add that later. And then we would be _more_ flexible, as you note,
since we could and/or more filters.

So I'm OK proceeding with this direction.
