Huh seems legit, I'm using boost and only up to the dash is highlighted, and the link doesn't work.

Yeah, I saw that thread, and can confirm the link doesn't work.

I sympathize with this bug as I wrote a big chunk of the code that does markdown to html conversion for piefed. I feel like every week or so some new edge-case pops up and I need to adjust my regex again. These community links are not standard markdown, so every app basically has to write their own bespoke solution.

Fixed for the next version, thanks for reporting.
