consider adjusting measure of pathway notes for better readability

[knksmith57]

The measure, or length of the lines of text, on pathway notes pages is a bit long (~153 characters / 31 words).

To make the long form notes easier to read and more approachable, consider capping their length to something closer to ~80 characters --even a reduction to 100 characters could provide a noticeable improvement for readers.
