* Improve get last commit using git log --name-status git log --name-status -c provides information about the diff between a commit and its parents. Using this and adjusting the algorithm to use the first change to a path allows for a much faster generation of commit info. There is a subtle change in the results generated but this will cause the results to more closely match those from elsewhere.
