Hi,

I have question re: Highline. In this code fragment, when running on  
MacOS/X:

```
    agree("overwite #{path}? y/<%= color('N', BOLD) %>", true)

```

{|q| q.default = false}

… The prompt is followed by a newline in irb/ruby. I can’t see an  
option in the docs to change this behavior. I’m trying to emulate the  
question when copying a directory tree like the Rails command or its  
generators do.

Some searching led me to think that the Termios gem may help, but if I  
try to install it (Ruby 1.9.2-p0), I get this:

termios.c: In function ‘Termios\_to\_termios’:  
termios.c:182: error: ‘struct RArray’ has no member named ‘ptr’

Thanks (Snow Leopard, BTW)

You just want to take the answer on the same line? Add some space after  
the prompt (at the end of your bold N) and HighLine should do the right  
thing for you.

Hope that helps.
