avoid trailing whitespace in zero-change diffstat lines
In some cases, we produce a diffstat line even though no lines have changed (e.g., because of an exact rename). In this case, there is no +/- "graph" after the number of changed lines. However, we output the space separator unconditionally, meaning that these lines contained a trailing space character. This isn't a huge problem, but in cleaning up the output we are able to eliminate some trailing whitespace from a test vector.
