Hey,

While I was viewing one of my diffs for a commit I got a

Expected "rename from ", but got "copy from si"

This error occurred because I copied pretty much my entire file from one from to another (but did a few changes, so git diff returned...

Similarity index can also be copy, it's not restricted to just renaming.

I'll see if I can get a pull request done. But how do you generally handle multiple options? I can't seem to find any other example. For now I just wrapped it in a try catch.
