If you do a checkout with 2 positional arguments and the first is a branch or tag:

git2cpp checkout v1.0 v2.0

then it looks like the second argument is ignored. Should we explicitly check for this and error out rather than silently ignoring the second arg?

That would be consistent with git behavior.

LGTM once the error handling is added.
