+ * and other arguments are used, any remaining input until the end of the string
+ * is considered part of a single CodeArgument, regardless of spaces, quoting,
+ * escaping, etc.
+ *
+ * This means commands can support crazy input like
+ *
+ *     parse function() { return "wheee\n"; }
+ *
+ * ... without having to put the code in a quoted string and escape everything.
