    usr.bin/undo: Use CMD_ITERATEALL
    
    CMD_ITERATEALL hasn't been used although -i and -a set
    cmd to CMD_ITERATEALL. This makes doiterate() less readable.
    Change (A) to (B) to make it more readable and maintainable.
    No funcional changes.
    
    =====(A)
    if (cmd == CMD_DUMP) { ... }
    else if (RB_ROOT(&tse_tree)) { ... }
    else { fprintf(stderr, ...); }
    
    =====(B)
    switch (cmd) {
    case CMD_DUMP:
        doiterate_dump(); break;
    case CMD_ITERATEALL:
        doiterate_iterall(); break;
    }
