Add some js buttons to diffs
Устаревшая версия за
If you are browsing a PR and go to the "files changed" tab, the file headers work like an accordion now! Click once to open, click again to close. And opening one doesn't close the others. There is also a "collapse" button added to the page.
This pairs nicely with github-wide userstyle https://github.com/mdo/github-wide
