Wrong traceback

[mrkn]

When an exception is raised in the code in a code cell, IRuby reported a traceback with wrong line numbers and needless traceback entries which is in pry.

For example, the result of In [4] shows such a traceback.

We need to reset line number every code execution and drop needless lines of the traceback.

I hope the error message looks like this.
