Hmph, this may probably depend on the version of asciidoctor, but I
am getting quite different output.  It looks very similar to what is
shown at https://git-scm.com/docs/git-clone/2.45.0.

Even more puzzling, with or without this patch applied, I do not see
any difference in the rendered output of samples I used, which were
"clone", which has the changes from 76880f0510c and "add", which
hasn't been broken by the series.

 $ make -C Documentation USE_ASCIIDOCTOR=YesPlease git-{clone,add}.{html,1}
 $ man -l Documentation/git-clone.1
 $ lynx Documentation/git-clone.html
 $ man -l Documentation/git-add.1
 $ lynx Documentation/git-add.html

The rendered result is bad in the same way with or without this
patch applied, and "git clone" manual page is simply incorrect by
mangling a handful of command line options.  A recent bug report in
the thread that contains

    https://lore.kernel.org/git/xmqqle1xjm1s.fsf@gitster.g/

gives us more details.
