Rails Console Question ?>

OS = CentOS-5.2
Ruby = 1.8.6
Rails = 2.2.2

This may or may not be intended behaviour.

$ script/console
Loading development environment (Rails 2.2.2)

?>

In short, I am getting a command complete prompt if I do not enter
anything on a line. To get out of it I have to C. I have been
working in the console recently and do not recall this behaviour. I
expected that a simple would yield yet another >> prompt like
below.

$ script/console
Loading development environment (Rails 2.2.2)

Is it my memory that is wrong or is there something odd about what I am
seeing in the console?
