If you use "git gui blame" or "tig blame", both have a "blame from parent commit" feature. This restarts the blame using the content as it was just before the answer you just got, so you can recursively dig. It's unfortunately a somewhat manual process.

There was a GSoC project to do what you asked, where you would indicate a set of lines and get a "git log"-like output of all the commits touching those lines. But there were some issues with the code, and it never quite made it upstream, I think. I'm not sure what the current status is. Cc'ing Thomas and Bo, who worked on it.
