I think you need a script to do what you want. I think this works...
Save the following script in ~/bin/git-rblame.sh, make it executable,
and then create a global git alias for it as follows:
$ git config --global alias.rblame '!~/bin/git-rblame.sh $*'
Then you can just use
$ git rblame -L /SUBLEVEL/,+1 -M Makefile
6e86841d (Linus Torvalds 2008-07-28 19:40:31 -0700 3) SUBLEVEL = 27
2ddcca36 (Linus Torvalds 2008-05-03 11:59:44 -0700 3) SUBLEVEL = 26
...
4c91aedb (Linus Torvalds 2005-06-28 22:57:29 -0700 3) SUBLEVEL = 13
^1da177e (Linus Torvalds 2005-04-16 15:20:36 -0700 3) SUBLEVEL = 12
