Firstly, patches 1-4 are obviously correct.

As for this patch, I don't think that using flags is the right way to do this. We are not under any size pressure for struct diff_options, and the additional options that we plan to add (color-moved-whitespace-flags and ignore-space-delta) can easily be additional fields instead.
