[PATCH] branch: return error when --list finds no matches

["Josh Hunt via GitGitGadget" <gitgitgadget@gmail.com>]

From: Josh Hunt <johunt@akamai.com>

Currently git branch --list foo always returns an exit status of 0 even
when the branch being searched for does not exist. Now an error is printed
and returns a non-zero exit status.
