[PATCH v4 0/3] diff: Add diff.orderfile configuration variable

The original purpose of this patch [series] was to allow specifying the "-O" option for "git diff" in the config.

In this version, I've revised the commit message for patch 2, changed patch 3 to use git_config_pathname() instead of git_config_string(), and removed the FIXME from patch 3's commit message.

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
