By the way, it would be good to find an example with "evil merge",
which means that the change to given line(s) is in the merge commit
itself.  Correctly simplifying history in such case might be
non-trivial.

Another example that it would be good to have is "history split"
example, which means the case where some lines were consolidated
(e.g. after refactoring), and some of lines in "preimage" come
from different lines of history.

This would help with writing tests for this feature (compare tests
for blame), although they are not in my opinion necessary for the
proposal itself.
 
I hope that all this cases would fall naturally from the
implementation.

my_git is not very descriptive... well, unless you would do your work
on GSoC2010/line-level-history-browser branch, or something like that.

It might be good idea to have repo.or.cz as an additional repository,
as a fork of git.git repo, and with SoC / GSoC labels.  See
http://repo.or.cz/w/git.git/forks?t=soc
