strbuf_check_branch_ref(): a helper to check a refname for a branch
This allows a common calling sequence strbuf_branchname(&ref, name); strbuf_splice(&ref, 0, 0, "refs/heads/", 11); if (check_ref_format(ref.buf)) die(...); to be refactored into if (strbuf_check_branch_ref(&ref, name)) die(...); Signed-off-by: Junio C Hamano <gitster@pobox.com>
