[PATCH v3 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, but I need help with the
relative path handling [RFC 3].

It also added tests for "git diff -O", which I have split out because
they are independantly useful [PATCH 1].

I also noticed that -O had terrible error handling and could only read
mmappable files, so I fixed that [PATCH 2].

  diff: Tests for "git diff -O"
  diff: Let "git diff -O" read orderfile from any file, failing when
    appropriate
  diff: Add diff.orderfile configuration variable
