Check for asciidoc, and if it exists check asciidoc version, setting
ASCIIDOC8 when needed.  Currently it just runs asciidoc in asciidoc7
compatibility mode (see: Documentation/Makefile).

Hmmm... perhaps ASCIIDOC8 should be called ASCIIDOC7COMPATIBILITY?
We should revisit Makefiles and configure.ac when asciidoc 9 gets
released.

This should be "git portability" portable, even if it is not portable
according to "instanely autoconf-like portable" rules  ;-)

That's "Check asciidoc version".

And this is "ASCIIDOC8=@ASCIIDOC8@", I think.

Will apply with the said fixups.

Thanks.

Yep. Sorry for mistake (autoconf <-> asciidoc).

Nope. ASCIIDOC8=@ASCIIDOC8@ is in chunk below, this is for [future]
detecting asciidoc binary (so you can drop this chunk).
