git cherry-pick fails when picking a non-ff commit that is empty. The advice given with the failure is that a git-commit --allow-empty should be issued to explicitly add the empty commit during the cherry pick. This option allows a user to specify before hand that they want to keep the empty commit. This eliminates the need to issue both a cherry pick and a commit operation.
