This uses the fixed rev-parse to allow passing diff options to the
underlying diff command. For example:
$ git diff -r HEAD
shows the output in raw-diff format, and
$ git diff -p -R HEAD | git apply
generates a patch to go back from your working tree to HEAD commit
(i.e. an expensive way to say "git checkout -f HEAD").
At the same time, it accidentally removes the use of shell arrays.
