Long lines (eg. Markdown documents) get truncated

Long lines of text get truncated.

For example, In https://gitlab.githistory.xyz/nyanpasu64/exotracker-cpp/blob/master/README.md, the Credits section has some long lines which get truncated. This is especially visible at timestamp on Sun Oct 13 2019.

I think the best solution is to either add horizontal scrolling (which interferes with the current keyboard shortcuts of using left/right to scroll between timestamps), or to enable word wrap.
