[PATCH v5 0/3] diff: Add diff.orderfile configuration variable

I expect you've figured out what this patch series is about by now. In this version, I've applied Junio's suggestions from the last version, and also the stuff from the FIXUP commit he made after my stuff in the branch he merged into 'pu'.

Samuel Bronson (3):
  diff: Tests for "git diff -O"
  diff: Let "git diff -O" read orderfile from any file, fail properly
  diff: Add diff.orderfile configuration variable
