Jean-Noël Avila e72c2d2e91 doc: git-diff: apply new documentation guidelines ...

The documentation for git-diff has been updated to follow the new
documentation guidelines. The following changes have been applied to
the series of patches:

- switching the synopsis to a synopsis block which will automatically
  format placeholders in italics and keywords in monospace
- use _<placeholder>_ instead of <placeholder> in the description
- use `backticks for keywords and more complex option
descriptions`. The new rendering engine will apply synopsis rules to
these spans.
- prevent git-diff from self-referencing itself via gitlink macro when
the generated link would point to the same page.
