Limit the additional informations to a certain amount of lines

[Eroui]

If it happens that your code outputs soo many lines (Large costume input for example), egor fetches the whole output and try to display it. This can slow egor from displaying the resulting output to the user.

A better way would be to display few lines around the difference between expected output and user output.

But sometimes you need to see the whole output.
