[PATCH resend] Disable asciidoc 8.4.1+ semantics for `{plus}` and friends

[Thomas Rast <trast@student.ethz.ch>]

asciidoc 8.4.1 changed the semantics of inline backtick quoting so
that they disable parsing of inline constructs, i.e.,

  Input:	`{plus}`
  Pre 8.4.1:	+
  Post 8.4.1:	{plus}

Fix this by defining the asciidoc attribute 'no-inline-literal'
(which, per the 8.4.1 changelog, is the toggle to return to the old
behaviour) when under ASCIIDOC8.

Junio, can this go in before 1.6.4?  Otherwise the docs will not be
rendered right with asciidoc 8.4.1 and newer.  I got hold of a machine
with asciidoc 8.2.7 and it does not affect the output there.
