Max Brunsfeld created
Previously, when highlighting editor rows with a color, we always
auto-scrolled to the first highlighted row. This was useful in contexts
like go-to-line and the outline view. We had an explicit special case
for git diff highlights. Now, part of the `highlight_rows` API, you
specify whether or not you want the autoscroll behavior. This is needed
because we want to highlight rows in the assistant panel, and we don't
want the autoscroll.
