How should I use git diff for long lines?

Question

I\'m running git-diff on a file, but the change is at the end of a long line.

If I use cursor keys to move right, it loses colour-coding—and worse the lines do

Eight years later I find a superior answer, from https://superuser.com/questions/777617/line-wrapping-less-in-os-x-specifically-for-use-with-git-diff:

git config core.pager `fold -w 80 | less`

Now you pipe the git diff through fold, first, then to less: wrapped, less page-height is correct, keep syntax highlighting.
