From 6f9a332144cda5f4d7e6e03c37fb17f8ffac1fe3 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 21 Sep 2011 20:19:38 -0700 Subject: [PATCH] branch: add read_branch_desc() helper function This will be used by various callers that make use of the branch description throughout the system, so that if we need to update the implementation the callers do not have to be modified.
