[StGit PATCH 0/5] Various cleanups

Some of these are very tiny, others are a bit bigger. They're all in kha/safe, since they should be perfectly safe.

Karl Hasselström (5):
      Let the caller supply the diff text to diffstat()
      Simplify editor selection logic
      Eliminate temp variable that's used just once
      Wrap excessively long line
      Create index and worktree objects just once
