This wasn't planned, and is just what the code happens to do. Instead, let's give the answer the user almost certainly wanted: the full count of objects. Note that there are more complicated cases around cherry-marking, etc. We'll punt on those for now, but let the user know that we can't produce an answer (rather than giving them something useless). We'll test both the new feature as well as a vanilla --count of commits, since that surprisingly doesn't seem to be covered in the existing tests.
