When I use `M = True` it should detect renames instead of add / deletions. However, when I use it, it doesn't return anything. Is this a bug or did I just misunderstand how to use it?\n\nThe thing I noticed in `git log -M` is that instead of `R` it shows me `R100` (not really sure whether it's normal or not):\n\n\u003e commit a8b61b9d18350a3d44e50fc9614279a2654b646d\n\u003e Author: ondrowan \u003c...\u003e\n\u003e Date:   Sat Nov 5 12:16:21 2011 +0100\n\u003e \n\u003e Moved thing\n\u003e \n\u003e R100    thing   newdir/moved_thing\n","author":{"url":"https://github.com/ondrowan","@type":"Person","name":"ondrowan"},"datePublished":"2011-11-10T20:56:56.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/36/GitPython/issues/36"}
