Fixed catching unnececcary exceptions Exception Abort can't be thrown, so it is useless. Catching SystemExit and KeyboardInterrupt makes little sense as the thread can be terminated by KeyboardInterrupt before or after entering the wrapped command processing function. So one have to handle these exceptions in his main function anyway. Catching any exception in order to print a message and re-raise it changes the standard behaviour and might seem confusing.
