From 26cdd1e7c7a21b6d71ebc201fc2472a6a68f5ce4 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 17 Dec 2006 18:08:52 -0800 Subject: [PATCH] avoid accessing _all_ loose refs in git-show-ref --verify If you want to verify a ref, it is overkill to first read all loose refs into a linked list, and then check if the desired ref is there.
