The docbook manpage stylesheets convert cross-references with format the
'section called “%t”'. I personally prefer the asciidoctor version, but
for now add a hack to minimize the diff.

Thanks to the extensibility of Ruby we can override corresponding method
in the man page converter.

This fixes doc-diffs like:

              Look for attributes in .gitattributes files in the working tree as
  -           well (see the section called “ATTRIBUTES”).
  +           well (see ATTRIBUTES).

This can easily be removed later once we are confortable with the
asciidoctor version.
