From 20b630aae924e35c24ee3d082362c36bee1c97b3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Thu, 3 Jan 2013 21:03:10 +0700 Subject: format-patch: pick up correct branch name from symbolic ref MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit find_branch_name() assumes to take refs/heads/. But we also have symbolic refs, such as HEAD, that can point to a valid branch in refs/heads and do not follow refs/heads/ syntax. Remove the assumption and apply normal ref resolution. After all it would be confusing if rev machinery resolves a ref in one way and find_branch_name() another.
