Subject: git-sugpatch: Print usage with no suggestion argumenet

Add `Options` to `Config` to allow us to get a usage string from a
`Config` instance, which is where we create `Options`.

Needed to remove the `Debug` derive on `Config` in order to add the
field as `Options` doesn't implement `Debug`.
