The AsciiDoc 7.1.2 configuration files included in the ELinks
source tree apparently aren't compatible with AsciiDoc 8.4.4:
[ASCIIDOC] doc/elinks.1.xml
FAILED: [listdef-bulleted] missing section: [listtags-None]
make[1]: *** [elinks.1.xml] Error 1
Fix this by including asciidoc.py from AsciiDoc 7.1.2 as well.
The build system now doesn't care at all whether the user has
installed some version of AsciiDoc or not.
In the past, we have hit annoying incompatibilities when
people have attempted to rebuild ELinks documentation
with new versions of AsciiDoc:
http://bugzilla.elinks.cz/show_bug.cgi?id=989http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491820
So now we bundle the configuration files from a known good version
to let ELinks documentation be built with them regardless of which
version has been installed on the machine.
