Could you give an example of using git range-diff? How do you go from
v1 of a patch (series) to a v2? Normally when asked for changes to a
patch (series) I do an git rebase -i (on the local branch I used to
develop the feature/bug fix) and split/commit all requested changes
and then sent the new patches with git send-email again. But I guess
to use/combine that with git range-diffs I should start creating new
local branches for each patch (series) in development?

Thanks,

Mark
