[PATCH 0/2] diff-merges: introduce '-d' option

This new convenience option requests full diff with respect to first parent, so that

  git log -d

will output diff with respect to first parent for every commit, universally, no matter how many parents the commit turns out to have.

It's implemented as pure synonym for

  --diff-merges=first-parent --patch

The first commit in the series tweaks diff-merges documentation a bit, and is valuable by itself. It's put here as '-d' implementation commit depends on it in its documentation part.

Note: the need for this new convenience option mostly emerged from
denial by the community of patches that modify '-m' behavior to imply
'-p' as the rest of similar options (such as --cc) do.
