Since the syntax is supposedly backwards compatible (Asciidoctor claims
this and backs it up through its tests), it should be possible to
provide for both a2x and asciidoctor. The Ubuntu buildbots could benefit
from this change as well.

The Lua documentation is part of the WSDG, I plan to make more changes
in that area, but the delay makes it mildly annoying.

The required changes should not be evasive, but I could not quickly find
how to to the modifications. The manual mentions "user-defined
configuration", but it is unclear how to do it exactly:
