Re: [PATCH 1/2] submodule: preserve all arguments exactly when recursing

> +# Emit a quoted version of the all argument suitable for passing to `eval`
> +# $@ = words to quote
> +#
> +# This is intended to be used like the following:
> +#   orig_args="$(quote_words "$@")"
> +#   # do some work that includes calling shift
> +#   eval "set - $orig_args"
> +#   # now $@ has been restored, suitable for passing to another command
> +#
> +# Note that you cannot simply save off $@ into another variable because
> +# the shell gives $@ and $* special handling in parameter expansion
