[PATCH v2 4/4] branch: remove negative exit code

["Glen Choo via GitGitGadget" <gitgitgadget@gmail.com>]

From: Glen Choo <chooglen@google.com>

Replace an instance of "exit(-1)" with "exit(1)". We don't use negative
exit codes - they are misleading because Unix machines will coerce them
to 8-bit unsigned values, losing the sign.
