Yeah, since there were a number of existing two-line headers
in the document, I thought it would be better to simply
update these to that form than convert the others.  We have
far more of the two-line form too, so it's more consistent
with the existing docs.

No doubt.  I'm sure that would be a long deprecation period.

Interesting.  I didn't notice the matching right hand side
while I was looking at the original asciidoc manual.

Seems like a good rule.  I presume that when in doubt, we
should look to the Asciidoctor reference for the current
best practice.
