[PATCH 0/3] format-patch: --interiff/--range-diff tweaks

This series addresses a few comments[2,3,4,5] which cropped up during review of the series which added --interdiff and --range-diff options to git-format-patch[1]. That series made it into 'next' before I could address the comments, so these patches (based upon 'master') make minor tweaks "incrementally" (over 2 years late).
