Fixing the working tree is easy, but when we read from a history that already records such an entry in an attribute file, it would become somewhat cumbersome. I wouldn't use "very hard to fix" to describe such a case. But the demotion to warning does make sense; let's do that in v184.108.40.206. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
