There are a number of very low-level configuration details which need to be managed precisely to generate a proper range-diff. In particular, 'diff_options' output format, header suppression, indentation, and dual-color mode must all be set appropriately to ensure proper behavior. Handle these details locally in the libified range-diff back-end rather than forcing each caller to have specialized knowledge of these implementation details, and to avoid duplication as new callers are added. While at it, localize these tweaks to be active only while generating the range-diff, so they don't clobber the caller-provided 'diff_options', which might be used beyond range-diff generation.
