[PATCH 0/2] line-log: avoid unnecessary full tree diffs

Line-level log can be very slow with rename detection enabled (and its enabled by default), which is caused by it using the diff machinery very inefficiently. The second patch fixes the issue and make it much faster, especially in large repositories.

This patch series is independent from my other patch series making line-level log incremental [1]. The two can be merged easily, as the changes to 'line-log.c' don't overlap, and the conflict in 't4211-line-log.sh' is trivial (both series add new tests at the end of that test script).
