Nice.  That one could likely be sped up by calling git-blame just once
on each file with multiple -L options.

Though actually with the current implementation of git-blame you are
likely faster for a large number of differences by doing each region
separately anyway since then the cost for digging through the history is
obviously O(n) for n consecutive runs on n chunks while the
administrative overhead for several chunks in a single run is O(n^2) at
the moment.
