The "plus" and "litdd" issues seem like they can be solved by doing:

  ASCIIDOC_EXTRA += -aplus='+'
  ASCIIDOC_EXTRA += -alitdd='\--'

Using origin/ma/doc-diff-doc-vs-doctor-comparison, you can do something
like

  ./doc-diff --asciidoctor --cut-header-footer foo bar --
--ignore-space-change --word-diff

to reduce the amount of noise in the diff by a great deal. Going through
the result, I noted two issues which should be fixed by Asciidoctor
1.5.7, according to some initial searching (but I haven't tested):

"--" renders as an em dash followed by a ";". Looks like it's
https://github.com/asciidoctor/asciidoctor/issues/2604

"&" turns into "&amp;". Seems to be known and fixed:
https://github.com/asciidoctor/asciidoctor/issues/2525

Plus a few other problems. There's the odd problem here and there, but
most of the diff seems to be a large number of occurences of just a few
issues.

It would probably be worthwhile to try 1.5.7+ to see how much that
improves things. Seems like you're already underway there.
