I was looking at https://en.wikipedia.org/w/index.php?title=ABCorp_(American_Banknote_Corporation)&curid=10095553&diff=845650854&oldid=845650777 on the web and could not find what the difference was. I eventually had to copy-paste the two text blocks to my desktop and diff them with emacs to find what had changed.

We should have some way to make small diffs like this more visually distinctive. Maybe use darker, more primary, colors? Maybe marginal indications on each line? I'm guessing that internally, we treat paragraphs as the smallest unit of text, not lines, so a per-line indication might be difficult, but it certainly would have helped in this case.

Suggestion to whoever triages this: if you've got 30-something eyes, you might want to ask somebody with 50-something eyes to help you with the triage :-)
