[PATCH v3 0/3] Update t40* tests to use modern style.

Update t4001 to use modern style.

Old tests were written in a different style than modern ones; for better readability and test error messages, update t4001 to the modern style.

(Note: I somehow munged the b4 state of this series; I've done my best to fix it, but there may be threading artifacts in the email.)

Mark C. Chu-Carroll (3):
  Update t/t4001-diff-rename.sh to modern style.
  Update t/t4009-diff-rename-4 to use modern style.
  Update t/t4010-diff-pathspec.sh to modern style.
