scm shell gets stuck in "..." prompt

The extra closing bracket doesn't generate an error.

Will return out of "..." but will otherwise stay permanently like that. Including if you close the connection, reconnect to the OC shell and enter the scm shell.

Is this with rlwrap, or without it? Without rlwrap, ctrl-C should break out of this behaviour, although I admit I have had to sometimes hit it repeatedly. I have noticed that rlwrap will eat ctrl-C instead of passing it through. Also -- last time I tested, it was before the change away from CSockets. It is possible that the sockets layer is eating the ctrl-C instead of passing it on to the scheme interpreter (which does clear this).

Without rlwrap this happens.

Yes, CTRL-C will escape out of this, so it's not a huge issue. The bug is more the fact that the prompt remains expecting input with "..." when the user terminates the connection and reconnects.
