Is there any way to get git to give you a commit log for just commits that touched a particular line in a file?
Like git blame, but git blame will show you the LAST commit that touched a particular line.
I'd really like to get a similar log of, not the list of commits to anywhere in the file, but just the commits that touched a particular line.
See also Git: discover which commits ever touched a range of lines.
Since Git 1.8.4, git log has -L to view the evolution of a range of lines.
For example, suppose you look at git blame's output. Here -L 150,+11 means "only look at the lines 150 to 150+11":
$ git blame -L 150,+11 -- git-web--browse.sh

And you want to know the history of what is now line 155.
Then, use git log. Here, -L 155,155:git-web--browse.sh means "trace the evolution of lines 155 to 155 in the file named git-web--browse.sh".
$ git log --pretty=short -u -L 155,155:git-web--browse.sh
