This is a question for others on the list rather than Leon - is it intentional that the plumbing diff commands respect GIT_DIFF_OPTS? If a script that wants to create a diff with a certain number of context lines runs `git diff-index -U <context>` is it helpful for that to be overridden if GIT_DIFF_OPTS happens to be set in the environment? Looking at the history it seems that environment variable used to be the only way to override the default context setting but that's not the case now.
