I see. My example is more like this:

 for i in `seq 1 20`; do md5sum - <<< $i; done > foo
 git commit -a -m foo
 for i in `seq 1 20`; do md5sum - <<< $i; done | sort > foo
 git commit -a -m foo\ sorted

i.e., the sort order of a block of lines was changed "in place". Here,
most of the lines are attributed to the last commit. Am I expecting too
much from git-blame to detect line motions in such a case?
