The -vv option used --verbose as its long form, which was identical to the long form of -v. Since the case statement matches top-to-bottom, --verbose would always trigger -v (VERBOSE=2), making -vv unreachable via its long option. The long form is renamed to --verbose=all to avoid the conflict, and the usage string is updated accordingly. Must be backported to 3.3.
