[PATCH v3 0/5] doc: git diff reformatting

This is the continuation of the editing of the manpages to reflect the new formatting rules.

Changes since V1:

 * restate the formatting rules in the message of the first commit
 * fix typos
 * convert more parts to backticked
 * filter out most annoying self-referencing links
 * propose to separate with 'or' the -1 --ours options and the likes

          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.
