line wrap in literal code blocks

[r-xue]

I notice that lines from a literal code block will be wrapped.
Is this done on purpose?

It seems that this is caused by line 153:word-wrap: break-word; in bootstrap-astrop.css.
Replacing it with overflow: auto; will show scrollbars for long code lines or log. I feel that this may look better? ( well, just a matter of personal preference)
