This is all correct. It mostly works, which is the main impediment to
further work :-) You can try it by merging
git://github.com/trast/git.git line-log-cleanup
It segfaults if you attempt to track more than one range, however.
I have started some rewriting, which tries to phrase it more in terms of
simple operations on sets of lines, and pushed that as
git://github.com/trast/git.git line-log-WIP
This was successful in that the newly written code is easier to read and
completely broken.
