No worries. Maybe I made the error in the original. What I had on my test system had the
brackets though, so I don't think so. Hopefully WordPress isn't auto-removing
brackets, but it does still remove leading # characters when I paste stuff into
pre-formatted blocks, so I'm not sure that I would rule out that possiblity.
Anyway, thanks for fixing it.
