Thanks.

Will queue with the following log message.

    submodule update: silence underlying merge/rebase "--quiet" is given
    
    Commands such as
    
        $ git pull --rebase --recurse-submodules --quiet
    
    produce non-quiet output from the merge or rebase.  Pass the --quiet
    option down when invoking "rebase" and "merge".
    
    Also fix the parsing of git submodule update -v.
    
    When e84c3cf3 (git-submodule.sh: accept verbose flag in cmd_update
    to be non-quiet, 2018-08-14) taught "git submodule update" to take
    "--quiet", it apparently did not know how ${GIT_QUIET:+--quiet}
    works, and reviewers seem to have missed that setting the variable
    to "0" (instead of "1" which is used when "--quiet" is given) has
    the same effect to pass "--quiet" to underlying commands.
