Magit[1] is also excellent. And like all good git tools it exposes a log of what it did. Unfortunately it doesn't work so great with megarepos, but I understand that's being worked on. One area where this tooling is vastly superior to the command line is adding hunks instead of files to a commit, making it much easier to have a sensible history while allowing programming in a more natural style.
