SideBySide2: Fill the browser width and display a margin
Use the line length preference to draw a margin line at that many
columns of text. This allows a user to configure their project's
preferred width (e.g. 80 columns or 100 columns) and see the margin,
making it easier to identify lines that run over that width.
Filling the browser available space with the CM3 instances each at
50% size allows the user to more easily view long lines if they
have a wide display, and better fit on more narrow displays by
splitting the available width at 50%.
