Are you trying to fix a GitHub markdown issue by getting it fixed in Redcarpet? GitHub doesn't use Redcarpet, unless you mean something else.

(I also didn't mean that `max_nesting` would be a fix for you as a user, by the way, I just wanted to throw it in as a pointer in case...

My apologies for such a long delay in responding to this PR. This library is in a somewhat interesting state, given Sidekiq changes since I last did any work on...

@mirague yep, that works fine, since it's the same as `concat`ing against the default. I wanted to avoid hard-coding the current set of defaults, which is why my work-around above...
