Hmm. I consider the "write NULs backward" strategy to be pretty idiomatic (you can find several similar ones grepping for `\[--` in the git codebase). But that may just be me (I didn't look, but it's possible I wrote the other ones, too :) ). I don't have a strong preference, though. What you've written is quite readable. -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
