At first glance this looks like a bug in grit. But according to https://github.com/mojombo/grit, it's no longer maintained. :(

I'm considering rewriting git-graph in Java using JGit (http://www.eclipse.org/jgit/), but have only just begun exploring that possibility.

Sorry I couldn't be more helpful ...
