The upstream branch <upstream> now defaults to the first tracked
remote branch, which is set by the configuration variables
branch.<name>.remote and branch.<name>.merge of the current branch.
Without such a remote branch, the command "git cherry [-v]" fails with
usage output as before and an additional message.

I'm not sure, whether the usage output would be still necessary.
