I'm using following code for detecting changes between commits:

diff=commit.diff(*parents,R=True,M=True)

Everything works ok in except of renames. When I useM = 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?

The thing I noticed ingit log -M is that instead ofR it shows meR100 (not really sure whether it's normal or not):
