[PATCH 0/2] Improve Git performance on big trees

The discussion about using Git on Gentoo comes up again [1] and it looks like we can improve Git a bit if user only works on some subdirectories. In such cases, Git still does whole-tree check, which takes quite some time. "git status" takes 3 seconds on my machine, but I suspect lstat() is not the only culprit, "git diff --exit-code" is about 1 sec.

These patches makes "git rm <path>" and "git status <path>" a bit faster. Almost 1 sec for "git rm foo" still seems too long though, probably due to writing a 9MB index.

  rm: only refresh entries that we may touch
  status: only touch path we may need to check
