Fixed textile in "A Better Ook"

Code seems to expand out to:

```ruby
a='p=0;t=""*30000;';
$<.each_byte{ |c|
  a << ({
    ?< => "p+=1;",
    ?< => "p-=1;",
    ?+ => "t[p]+=1;",
    ?- => "t[p]-=1;",
    ?[ => "while t[p]>0;",
    ?] => "end;",
    ?. => "putc t[p];",
    ?, => "<a href=\"http://c\">t[p]=STDIN.getc||0;</a>" || ""
  })
};
eval a
```

Madness.
