Of course; that is the breakage you are trying to fix, no? My comment was that I understand you are trying to, but the patch is not actually fixing it. If anything, it is making it worse. Earlier we would have got a false breakage that would make people notice and take a look. With your patch applied, we instead would let a breakage in parts earlier than these "unset VAR;" go unnoticed, no? -- 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
