 * This routine is similar to the UNIX 'strcat' except that the pointer
 * it returns is to the end of the resultant string instead of the
 * beginning. This is useful when several 'strcat' calls are used in
 * succession to build a string. With the UNIX version the entire string
 * must be scanned from the beginning to find the end. With this one
 * we already have the end after the first call.
