4076: Make it easier to view "context" around diff comment fragment


What version are you running?


What's the URL of the page this enhancement relates to, if any?


Describe the enhancement and the motivation for it.

When viewing a diff comment on the reviews page, right now the 4 clickable things that expand on hover are:

  • show 20 previous lines
  • show all previous lines
  • show all next lines
  • show 20 next lines

None of these options provide a quick one-click way to expand "context", which is what I want to see when looking at an issue.

It would be nice if there was a clickable button (that didn't require hovering, or waiting for expando animations or anything) that was just "Show [N] Context", to show N previous and following lines. Ideally N would be a user preference.

Please provide any additional information below.
