(You may also want to combine this with -l and/or -C). You shouldn't need to specify "-M" with --follow, as the diff done by try_to_follow_renames() turns on rename (and copy) detection explicitly. I suspect the problem is that git-log does not do merge diffs at all by default, and you'd need "-c" or "--cc" (or maybe even "-m") to turn them on. I wouldn't be surprised if there are other problems where that code path isn't quite ready to handle merge commits, though. -Peff
