[git] attributes : diff

From 0e8ee18#commitcomment-28734737

Git offers fine-grained control over diff visualization (among other things) on a per-repository basis, see https://git-scm.com/docs/gitattributes#_generating_diff_text.

Note that all this was (maybe?) lost with latest changes:

Ver differencias por palabras en lugar de líneas (probado también con git show): git diff --word-diff=color --word-diff-regex=.

Note: these are all notes to self. ^^
