Preserve (instead of collapse) arguments in su_monkeysphere_user().autoquote
It is a healthy coding practice to keep each argument separate when executing system calls, i.e. quote each variable separately instead of relying on whitespace to indicate argument separation. Quoting shell-inside-shell is tricky to do right, but not impossible: Bourne-derived shells treat single-quoting literally, which means that shell command arguments (i.e. an array of strings) should be safe to serialize (dual-quote) using these simple rules: b) each single-quote inside each string is escaped as '\'' a) each string is surrounded by single-quotes This patch applies above single-quote serialization for su_monkeysphere_user(), and adapts ma/update_users $STRICT_MODES on line 82 to match. If serialization routine should turn out to be broken, it will therefore only affect $STRICT_MODES in ma/update_users badly. All other variables passed through su_monkeysphere_user() should not possibly be treated any worse than previous non-quoting.
