From 5bdd8d4a3062ac8f29ec511fecb85049f6ff3ecc Mon Sep 17 00:00:00 2001 From: Clemens Buchacher Date: Wed, 5 Nov 2008 21:55:53 +0100 Subject: [PATCH 1/2] do not force write of packed refs We force writing a ref if it does not exist. Originally, we only had to look for the ref file to check if it existed. Now we have to look for a packed ref as well. Luckily, resolve_ref already does all the work for us.
