How do I "git blame" a deleted line?

git blame is great for modified and added lines, but how can I find when a line that existed in a specific previous commit was eventually deleted. I'm thinking bisect, but I was hoping for something handier. (Before you ask: in this case, I just did a git log -p and searched through for the code line and (a) some idiot had just deleted the vital line in the previous commit and (b) I was that idiot
