I was looking for the same thing for some time now, and I have not found a
single program that does it.  But I discovered something even better!

Git allows you to grep through all diffs. In your example, I saw the comment
"bezier" above the code of interest, and, using this as an "anchor keyword",

git log -p -Sbezier

finds just the change you were looking for. It shows both commit message and
patch, and is quite fast.  This command opens a tiny new paradise for
history digging.  I'm finally starting to enjoy git...

bye,
Martin
