I have concern: I currently generate manpages with Asciidoctor+xmlto. Does
this change affects people using xmlto?

At what version of Asciidoctor the apostrophe handling is corrected?

Maybe when distros upgraded shipped Asciidoctor version to 2.0, we can
bump the version requirement.

I think "ASCIIDOCTOR_TO_MAN" would be good alternative name here, since
this command generates manpage from asciidoctor.

The wording should be "...instead of building manual pages from DocBook with
xmlto".

Thanks for my review.
