Subject: submodule: preserve all arguments exactly when recursing

submodule: preserve all arguments exactly when recursing

Shell variables only hold strings, not lists of parameters,
so $orig_args after

orig_args="$@"

fails to remember where each parameter starts and ends, if
some include whitespace.  So

git submodule update \
--reference='/var/lib/common objects.git' \
--recursive --init

becomes

git submodule update --reference=/var/lib/common \
objects.git --recursive --init

in the inner repositories.  Use "git rev-parse --sq-quote" to
save parameters in quoted form ready for evaluation by the
shell, avoiding this problem.
