commit: support a root commits A root commit is a commit whose branch (usually what HEAD points to) doesn't exist (yet). This situation can happen when the commit is the first after 1) a repository is initialized or 2) a orphan checkout has been performed. Take this opportunity to remove the symbolic link check, as git_reference_resolve works on OID refs as well. Signed-off-by: Carlos Martín Nieto <cmn@elego.de>
