Yeah, I don't think I can really disagree with that. I had some vague notion that it opens the path for adding orthogonal options later. But really, I'm not sure that any exist, since they are, by definition related to the diff. Unless we want to have diff driver options for how to do a binary diff. > For the same rationale, if you have .textconv, I think it is natural for > us to say that you do want to see the change in the textual diff format. > So I'd agree that you can get rid of this .binary business by saying that > having .textconv marks it diffable (IOW, I think your first alternative > makes more sense). OK. My re-rolled series will keep the assumption that a diff=* attribute makes a file non-binary. However, I will still include the 'binary' struct member in the diff driver, as it greatly simplifies the code. It is trivial then to support "diff.*.binary" (which would default to 'false') if we feel like it. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
