Adam, Just started getting familiar with rush and when trying to exit using #finish() an exception is thrown.

Is #finish the appropriate method call for exiting ?

Cheers! sinclair

PS the work-around is #exit! rather than #exit in shell.rb #finish()

Actually, Ctrl-D is the standard method of exiting the shell. But I agree people will expect the exit command to work as well, so I just added it in the latest git revision.
