Benchmarks against Git tuned for large repositories (refs #41) 5ae7533f1888

A Git column tuned as Git recommends for large repositories
(feature.manyFiles, core.untrackedCache, a commit-graph; no fsmonitor,
which has no daemon on Linux in Git 2.53). Tuned Git is ahead of oxy on
clean and one-file status, diff, log and blame; oxy beats Git as it comes
on status only.

tuned as Git recommends for large ones: `feature.manyFiles` (index v4 and
