I'm not sure if is important here, but for the record.
You should keep changes like this in a separated commit, something like "remove unused code", because is a change that is not related with the rest.
Also, `git blame` and `git bisect` works much better with smaller commits.
I saw this article some days ago that made me think on it -> http://www.lullabot.com/blog/article/git-best-practices-workflow-guidelines (Small, logical commits)
