To Artifact [42cc4a7a9d]:

• File src/diff.js — part of check-in [63a5c754fd] at 2021-09-03 23:00:50 on branch diff-color-enhancements — Draw a thin box around diffs in the default skin (per [forum:/forumpost/a42aade32dd9d42|forum post a42aade32dd9d42]). Show ellipsis at the tops and bottoms of files, if warranted. Fix a problem with "diff.js" that was failing to link all scrollbars associated with a single diff. (user: drh size: 2244)
