[PATCH] doc: fix asciidoctor synopsis processing of triple-dots

[Jean-Noël Avila <jn.avila@xxxxxxx>]

The processing of triple dot notation is tricky because it can be
mis-interpreted as an ellipsis.

Another issue is that the formatting of synopsis paragraph in
Asciidoctor spits out another asciidoc formatted text where verbatim
text formatted with backquotes must have surrounding separators in
order to be properly detected, even if they are sticking to another
text.

The special processing of the ellipsis is now complete and takes into
account the case of `git-mv <source>... <dest>`
