blame: pay attention to --no-follow
If you know your history did not have renames, or if you care only about the history after a large rename that happened some time ago, "git blame --no-follow $path" is a way to tell the command not to bother about renames. When you use -C, the lines that came from the renamed file will still be found without the whole-file rename detection, so it is not all that interesting either way, though.
