I am competent enough to read c and note that none of those changes you highlighted have functional impacts. They were largely cosmetic changes (e.g. removing an else condition by assigning the inclusive flags to a variable). I saw one change that looked like a performance improvement (an early loop exit break added). I will also note that rsync has a test suite and running tests as "integration" style testing is more common of shell utilities than writing gobs of unit tests. I would have liked to see an additional targeted test written for the CVE in this patch though.
