Robin reported that
git submodule foreach --quiet git pull --quiet origin
is not really quiet anymore [1]. "git pull" behaves as if --quiet is not
given.
This happens because parseopt in submodule--helper will try to parse
both --quiet options as if they are foreach's options, not git-pull's.
The parsed options are removed from the command line. So when we do
pull later, we execute just this
git pull origin
When calling submodule helper, adding "--" in front of "git pull" will
stop parseopt for parsing options that do not really belong to
submodule--helper foreach.
PARSE_OPT_KEEP_UNKNOWN is removed as a safety measure. parseopt should
never see unknown options or something has gone wrong. There are also
a couple usage string update while I'm looking at them.
While at it, I also add "--" to other subcommands that pass "$@" to
submodule--helper. "$@" in these cases are paths and less likely to be
--something-like-this. But the point still stands, git-submodule has
parsed and classified what are options, what are paths. submodule--helper
should never consider paths passed by git-submodule to be options even
if they look like one.
The test case is also contributed by Robin.
[1] it should be quiet before fc1b9243cd (submodule: port submodule
subcommand 'foreach' from shell to C, 2018-05-10) because parseopt
can't accidentally eat options then.

I'm not trying to fix "git pull --rebase --quiet" (or "git rebase
--quiet" in general) in the end, since that looks like a whole other
can of worms.
Not only git-rebase--preserve-merges.sh needs to respect --quiet (but
which case? I don't have enough experience to say) but sequencer.c
may need to be scanned too.
