Re: [PATCH 3/4] avoid trailing whitespace in zero-change diffstat lines

Jeff King [off-list ref] writes:

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.

This is why I love your patches.  Not merely fixing superficial issues but
doing so with _real thinking_ ;-)
