I recently added some tests for show-branch, see the tip of
ab/show-branch-tests. This seems like it would be clearer to both you &
reviewers if we first checked & test_cmp'd the reflog behavior of "git
show-branch" in some "here's how it works now test", then made whatever
non-changes to the format done here.

Presumably this newline mystery would become clear once we'd have
coverage of its reflog codepaths.
