From b37a562a1097af7403c649a5f903a93acaf279e8 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 11 Sep 2006 20:10:15 -0700 Subject: [PATCH] Add support for negative refs You can remove a ref that is packed two different ways: either simply repack all the refs without that one, or create a loose ref that has the magic all-zero SHA1. This also adds back the test that a ref actually has the object it points to.
