rev-list: check reflog_info before showing usage
When git-rev-list sees no pending commits, it shows a usage message. This works even when reflog-walking is requested, because the reflog-walk code currently puts the reflog tips into the pending queue. In preparation for refactoring the reflog-walk code, let's explicitly check whether we have any reflogs to walk. For now this is a noop, but the existing reflog tests will make sure that it kicks in after the refactoring. Likewise, we'll add a test that "rev-list -g" without specifying any reflogs continues to fail (so that we know our check does not kick in too aggressively). Note that the implementation needs to go into its own sub-function, as the walk code does not expose its innards outside of reflog-walk.c.
