It works fine for me with asciidoc 8.6.7. <sigh>

I would think the "inline literal" syntax started in 8.2.5 would take
care of it; maybe there were some bug fixes, considering how new it was
in your version.

I also think switching "!" to `!` is a slight regression; it will change
fonts in the HTML version, but usually not in the manpage, and the loss
of the quotes makes things harder to read. I would use both, and it does
not hurt to also spell out the name of the punctuation.

So this:
