Subject: how to track the history of a line in a file
Message-ID: <alpine.DEB.1.10.0901021405460.21567@asgard.lang.hm>

I have a need to setup a repository where I'm storing config files, and I 
need to be able to search the history of a particular line, not just when 
the last edit of the line was (which is what I see from git blame)

I'm not seeing a obvious way to do this, am I missing something or does it 
need a non-obvious approach?

for example, if I do

git blame -L /SUBLEVEL/,+1 -M Makefile

on the linux kernel it currently shows

57f8f7b6 (Linus Torvalds 2008-10-23 20:06:52 -0700 3) SUBLEVEL = 28

what I would want it to show would be a list of the commits that have 
changed this line.

It looks like I can write a script to do this

git blame -L /SUBLEVEL/,+1 -M Makefile 57f8f7b6^
6e86841d (Linus Torvalds 2008-07-28 19:40:31 -0700 3) SUBLEVEL = 27
git blame -L /SUBLEVEL/,+1 -M Makefile 6e86841d^
2ddcca36 (Linus Torvalds 2008-05-03 11:59:44 -0700 3) SUBLEVEL = 26

etc.

is there a better way to do this?
