A quick suggestion - does setting the ribbon_frac to something like 0.8 improve things?
Nope. The ribbon (IMO both an undescriptive name and underdocumented) only constraints the number of non-indent characters per line. So it makes the line breaks in different places, but the underlying problem of it not knowing where lines should be broken remains.
The Show instance for wl-pprint's Doc uses 0.4 which I've found too low.
It's off the subject, but I alway thought 'ribbon' was odd as the single knob available. I never really saw a rationale for why it's so important. The old Hughes-PJ paper says it looks nice to have a "ribbon" of text snaking across the page, but I think it looks nice to preserve vertical space by filling lines as much as possible. Difference of opinion I guess.
