The interim single-liner '?' fix resulted delete entries that should not have emitted coming out in the output as an unintended side effect; I caught this with the "rename" test in the test suite. This patch instead fixes the code that assigns the status code to each filepair. I verified this does not break the testcase in udev.git tree Kay Sievers gave us, by running git-diff-tree on that tree which showed 21 file to symlink changes.
