Merge branch 'sg/diff-multiple-identical-renames'
"git diff -M" used to work better when two originally identical files A and B got renamed to X/A and X/B by pairing A to X/A and B to X/B, but this was broken in the 2.0 timeframe. * sg/diff-multiple-identical-renames: diffcore: fix iteration order of identical files during rename detection
