My personal favorite is `git log -p --` because it actually shows you the content that changed.

Or, to show you what changed on each given single line, use `git log -p --color-words --`. Far more useful for long lines, IMO.

I'm also a fan of `git log -LN,N:filename`, where N is a line number. It gives you a log of that particular line number. It's like `git blame` but better.
