c.format = :cue; "r" (restart) continues next test instead of restarting

In the block arg to Turn.config I set "c.format = :cue".  When a test fails and the runner pauses, one of the possible inputs is "r" for restart:

```
[c,i,q,r,t,#,?] ?

    c continue
    r restart
    i irb
    b backtrace
    # backtrace lines
    q quit
    ? help

[c,i,q,r,t,#,?] 
```

But "r" for restart works just like "continue".  Isn't it supposed to restart the failed test?
