I wonder if I should have simply gone this route instead of adding warn_on_object_refname_ambiguity, and then people who want "cat-file --batch" to be fast could just turn off core.warnAmbiguousRefs. I wanted it to happen automatically, though. Alternatively, I guess "cat-file --batch" could just turn off warn_ambiguous_refs itself. -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
