[(+ 2 _ a very long bracket fn causes extra parens)]t
That bug must have creeped in because it calls ppr again on the body if it needs to wrap. I'm not 100% sure how to fix it though. Maybe print the first and then map ppr over the rest?
The question is, how to get br-fns to properly indent their bodies. Maybe ppr needs an option to avoid printing the parens.
