This series depends on ort-perf-batch-10[1], and obsoletes the ort-remainder topic[2] (that hadn't been picked up yet, so hopefully this doesn't cause any confusion) With this series, merge-ort is ready for general usage -- it passes all tests, passes dozens of tests that don't under merge-recursive, and merge-ort is is already significantly faster than merge-recursive when rename detection is involved. Users can select merge-ort by (a) passing -sort to either git merge or git rebase, or (b) by setting pull.twohead=ort [3], or (c) by setting GIT_TEST_MERGE_ALGORITHM=ort. Changes since v1: * subsumed the ort-remainder topic (the first 10 patches), which has already been reviewed by both Ævar and Stolee[2]. * the next two patches were the original v1, reviewed by Stolee * the final patch is new and adds testing.
