Can't scroll both directions with vertically and horizontally large paste in desktop / mouse

[pasnox]

The paste is shown in a zone where the width is controlled by the client size width, but the height is not.
Then one need to fully vertically scroll to the end to be able to scroll horizontally, very annoying.

Maybe lines should just be wrapped instead? I find the horizontal scrolling is usually not what the poster intended. Text wrapping is a trivial change – f5aff9d.
