doc: git-clone fix discrepancy between asciidoc and asciidoctor

Asciidoc.py does not have the concept of generalized roles, whereas
asciidoctor interprets [foo]`blah` as blah with role foo in the
synopsis, making in effect foo disappear in the output. Note that
square brackets not directly followed by an inline markup do not
define a role, which is why we do not have the issue on other parts of
the documentation.

In order to get a consistant result across asciidoctor and
asciidoc.py, the hack is to use the {empty} entity
to split the bracket part from the inline format part.
