1106 * This avoids multiple allocation. Also, when we've called this
1107 * routine command-line string options have already been applied so we

1109 *
1110 * So, search in resources from most to least specific.
1111 *
1112 * Also, use a special sub-class so that we can use either or both of
1113 * "XTerm" and "Rxvt" as class names.
